Describe your problem, including steps to reproduce it

Not a clue on how to reproduce it.

Mainly concerned about what I could do to get the server back online :/

Any other comments?

This might actually be related to another issue reported around the same time the server started crashing.
EnigmaticaModpacks/Enigmatica5#526

Right... build 80 should fix it properly. The Amadrone should no longer attempt to collect more than 36 stacks a time when restocking player offers. So any excess will be left in the chest, and collected on the next restocking run (30 seconds later IIRC).

I don't think it's related to that other issue, but it did look familiar, and I remembered this got reported in 1.12.2 as well - #399. I added a workaround there (could never trace why it was crashing... read the issue), but I stopped it crashing completely.

Looks like the "fix" didn't make it in 1.15, so I'll get it in now.

OK, build 78 from https://jenkins.k-4u.nl/job/PneumaticCraft-Repressurized-1.15/ should get you up and running again. I'll be getting a 1.5.1 release out fairly soon.

Build 78 seems to have loaded up just fine. Thanks for the super fast response :)

OR NOT LOL

Looks to me like the same issue?

Hmm. Only possibility now is that there are more than 36 itemstacks in this order... wtf? I can add a workaround for this too, but no clue how it's gotten into this state. Could you upload your config/pneumaticcraft/AmadronPlayerOffers.cfg file to somewhere I can take a look at it?

I was just about to do that.

Can't see anything obviously wrong there, but when you start up with build 79 (available now), check for a "retrieveOrderItems: unexpected size" log message in the server log. Will be interested to see which order is triggering that...

Only order that looks possibly suspicious is:

{
      "id": "pneumaticcraft:mutetiefling_1602415143",
      "input": {
        "type": "ITEM",
        "id": "minecraft:emerald",
        "amount": 16
      },
      "output": {
        "type": "ITEM",
        "id": "simplefarming:fish_sandwich",
        "amount": 64
      },

If those fish sandwiches don't stack (do they?) that would end up with a 64-long list of items. The 36 limit is in place since that's the max size of a drone's inventory, with the full 35 inventory upgrades.

[m←[1;31m[13:17:08] [Server thread/ERROR] [pneumaticcraft/]: retrieveOrderItems: unexpected size (37) for itemstack list for offer 197 x 12 plastic @ DimensionType{minecraft:overworld} BlockPos{x=681, y=65, z=864}

Ooops!

I had tossed in about 2 inventories worth of plastic into a diamond chest for the amadron to come and pick up. Not even buying anything

Yeah... that's it ;( 2364 plastic = 37 stacks.

I need to handle that better, clearly...

Fixed in 1.5.1 release
(and 2.4.3 for MC 1.16.3)
