Sometimes when you try TFC with other mods and it does not recognize which item size give to him the game just crash.

Here is the log:
crash-2019-07-19_12.24.14-client.txt

For reference: Advanced-Rocketry/AdvancedRocketry#1639

I'm fairly confident that the issue is on Astral Sorcery's Advanced Rocketry's side here. That said, I've been unable to reproduce this so I can't say for sure.

AR devs confirmed to me that the problem is with TFC. When the mod tries to give to Advanced Rocketry space suit an item weigh.

Btw i don't have Astral Sorcery in my pack.

Yeah, I meant Advanced Rocketry. TFC doesn't assume that any item has a special size - it attaches a capability. If AR's space armor has a problem with that then it's not a TFC issue.

Also: Side note: Only Z devs, I moderate the discord and help with issues when I can.

Ok, sorry. I thought you are a Dev. Since you answered my question.
