The save file of your character which is in :
C:\Users\ USERNAME \Documents\My Games\Grim Dawn\save\user\ _charactername
So you should zip and upload the directory _charactername
I recommend you post a link to GrimInternals on you first post at the end, it’ such an amazing QoL for this mod with everything that is auto pick up (souls, component, currency, Grim souls/essence soul buffs…) it’s much more smooth not having to stop to pick up all these buffs/currency. I completely forgot about it!
I also experienced some crash when killing monsters, maybe it could be that some affixes on some loot that have proc skills with autocasft features or maybe it’s because of some files missing/incorrect pah I don’t know, will test with next version.
Here some affixes that could have caused the crash when dropping, I don’t know if these affixes where changes in the mod :
Or it could be some missing pet bonuses, it happened in the D3 mod some time ago:
A fast way to test this mod is in Ultimate difficulty use GDSTash to uncheck the Devotion Shrine in Act 1 “Burial Hills” (Ultimate) then go to the waypoint and directly in the cave to spawn all these monsters, they drop a lot of loot and sometimes spawn Nemesis/Om boss so it often crashes there.
