Aragnier, in your case the code did need to be changed on modded code at those lines. You can change in the error lines listed In that file on your error code, but the issue with changing that file directly (instead of the file line in the mod itself) is that the next time you enable or disable a file that overrides that file, any changes you’ll have made directly to that file will be overridden. Sorry I wasn’t clear about which file needed changing in your case, but those line numbers corresponded to the mod’s line numbers for that file (in mods/aricsexpansion/scripts/mansion.gd)
I’ll examine that issue when I get around my coding PC. Just to clarify, everything else is working?
