Crash report affecting all 3 auto saves and both manual saves which have 10 hours between them. The bug effects all of them within 2 seconds of world load. Can provide world file and mods list if needed. world crashes for myself and other person i was playing with
error message is:
Carna (0.2.16)

carna/control.lua:1455: bad argument #1 of 3 to 'insert' (table expected, got nil) stack traceback:
[C] : in function 'insert'
carna/control.lua:1455 in funtion <carna/control.lua:1453>

Was this after Carna was added to your modpack, when Carna was generated, or before Carna was generated?

Well I pushed an update out, from the very little information I have to work with, my only conclusion is that a table likely didn't generate when it should have, so I moved them around. If it still doesn't work, I'd recommend either removing the mod, loading the world up, then saving it, and then re-add the mod to trigger the script to fire. Otherwise I might likely need your save data to see what's going on.

The modpack was started on that world and ran fine for 30 hours then suddenly all the save files had that same error even the file from 10 hours before.
After posting here i had removed the mod and the worlds worked again.
I have updated your mod and readded it and it does not crash now.
Thank you for the quick push fix if it happens again i will post again here.

Alrighty then, glad that may have helped.
