Do you have any additional mods activated as well? And out of curiosity, did you do the final suggested step if deleting or copying over your Strive/backup files as well? It looks like upgrades.gd reverted to vanilla for you
Nope, no additional mods (might add in improvedrandomportraits though, if it works). Re-installed the mod with new instructions and no longer get the error and see lab upgrade now, thanks!
