[Bug] Beavers and haulers only carry min amount of supplies

19 votes

I've notice in my game, that the hauler beavers will go pick up water from a pump station, but they only grab 1 water worth about 2/23kg leaving the building with 14/15 waters available. The haulers should be grabbing everything they can from a pickup.

I agree as well as builders grabbing as much as they can to transport items to a construction site. A builder should be able to fil 10 dynamite and then go back and construct.

Are your water tanks near full capacity? There may be a tank that had a single beaver drink from it, and is now being topped-off.

I agree with the suggestion, but this isn’t a bug, per say. The issues behind this behavior seem to be either when they were queued up to grab the resource, only one was available at the time (and others subsequently get queued up for the rest), and/or the destination storage can only fit 1 more. It’s a general efficiency issue with how the AI handles everything.

Whenever beavers carry anything that is not logs, the only carry a single item instead of filling the entire stack, making strength stats irrelevant.
This applies to beavers assisting carrying goods, haulers (likely a bug) and and Beavers working in a distribution post, even as there is a whole stack available for transportation.

This has been happening to me as well.

I considered the suggestion of @FuryoftheStars, but I think this is actually a bug (or at least not WAI). I just started transferring goods from a warehouse complex I'm going to demolish to a new one I just built, and I'm watching a line of about 15 haulers carrying one bag of flour each. (Sometimes they do fill up, particularly with fully processed food, but other resources like gears often get carried just one or two at a time.)

There's also the somewhat surreal sight of a cloud of beavers transferring goods from one underground warehouse to one newly-built one immediately adjacent. At first I thought one might have more than the desired amount of something and they're trying to balance it, but that doesn't always seem to be the case.

Actually, what Fury said isn't entirely untrue either. Some of said flour is coming directly from the gristmill which produces one at a time. Flour-laden haulers walk right by an open bakery (marked as priority), preferring to first store the flour in the warehouse on the other side of the city before carrying it all the way back, so clearly there is also optimization to be done.

I think this is a bug, not an availability issue. My district crossing workers are grabbing 1 water at a time from 3 medium tanks on the exporting side. The medium tanks are full and within 5 path blocks of the crossing, the district crossing on the importing side has 0 or 1 water and no other items as they do this. On the importing side, there are many medium water tanks that range from empty to half full, and the 1 water is moved within seconds. The water export threshold setting on the exporting side is set to 25%, with 84% available. On the importing side, water is set to import always.
Each day the beavers start transporting in increments of 14 water per trip, then within 2 or 3 trips the amount of water they carry drops to 3, 2, and finally 1 for the rest of the day. After watching this for several days, the reduction from 14 to 1 happens when the export side is removing the water while the importing side is providing the water.

with district crossings, need to also know how much storage capacity was on the import side. it's balanced by %.

I have 10 medium tanks of water in the import district, so that district had 1.9k of 3k water. The exporting district had 5 full tanks of water, so 1.5k water.
In the exporting district I have one water tank by the water pumps set to Supply, so that my haulers move the water out of that tank. I have another water tank by the houses for the local beavers set to Accept. Finally I have the three water tanks in the image above, next to the crossing, set to Obtain. All except the tank for the local beavers, set to accept, are prioritized by haulers. I have found that if I rotate one of the three tanks next to the district crossing to Supply, the district crossing will try to keep the export side at 30 water. If I leave all 3 set to Obtain, the 1 water per delivery bug shows up every day. Because switching between supply and obtain causes the district crossing to behave differently, I believe this is a bug. imo, Supply, Obtain, and Accept should only be for the haulers.

no. you're misunderstanding how supply interacts with things. haulers are not the only one who care about that.
supply and empty takes the max capacity out of consideration for district distribution while also actively pushing their contents to other storage containers.
obtain is hauler only
accept affects both

that said, i think you should be exporting a little more water currently than you are though if i'm reading everything correctly, but it's hard to tell with only the information i can glean here-it's a bit hard to figure out what you're saying.

i wonder if the crossing workers are trying to evenly distribute to all your tanks. pretty sure it counts anything that's being held by a beaver until it's delivered. try setting that half full tank on the importing side to 'supply' to push the contents to other tanks with haulers and see if anything changes.

if you make a change, it's going to take a while to balance out! an intial surge when you set something to supply on sending side will take a while for it to get back into equilibrium so saying it tries to keep it at 30 means nothing if you don't also give it time to stabilize.
