[0.17.2] Crash with specific save: "Unit number cannot be zero when comparing entities."

[Liuhu]

We started a new save with a friend using the Steam Connect multiplayer. After around 6 hours my game crashes almost constantly. I think it has occurred always right when I clicked an item in my inventory or quick bar. I tried the same save in single player and the same thing happens there as well.

I tried killing the character to "reset" it and it didn't help. Game crashed again after a few minutes.

If there's anything else that I could provide to pinpoint the bug better, please ask and I'll try my best to provide it.

[Liuhu]

I tried the new 0.17.3 and the same happens again. The game is unplayable because of this. I can get you better logs if someone tells me what "atos" is and how to install it.

[Liuhu]

I can now reliably crash the game in the attached save file by simply opening the inventory and clicking the Gun turret (2 in inventory). Crash log below. If you need more information, please ask and I will try my best to answer and deliver more details.

0.17.5: 66737, 66742

[Liuhu]

I tested and the same freeze still happens in 0.17.5 with the attached save when I click the Gun turret in my inventory.

[Rseding91]

Thanks for the report however I can't reproduce any crash with the save doing the steps you list.

Can you reproduce it on a new save file? I notice that all of the linked reports are on Mac so it might be something there.

[Liuhu]

I tried another save but couldn't get it to crash in a reasonable time. The crash might have something to do with blueprints as said in one of the linked threads. The original save doesn't crash either (at least in a short test) if I delete my blueprints.
