I get the same error.
These modules are active in my game:
autoharvest_mod.smod
biome_crops_mod.smod
debugtools.smod
extraload.smod
fruit_trees.smod
lostems.smod
margin_removal_mod.smod
radiant.smod
rayyas_children.smod
roll_for_need.smod
stonehearth.smod
SuperMod1000.smod
townmonitor.smod
tree_stump.smod
unitframeacitivitymod.smod
I got another bug that may or may not have a connection to this one:
co-routine failed: stonehearth/lib/game_master/game_master_lib.lua:114: root node entling_ritual_site not found
and it’s posted here: Error and then game halt\crash - root node entling_ritual_site not found
I’ve added this just in case there’s a connection ,If you don’t think there’s a connection just ignore.
