Sorry my debug logs were 28mbs and I couldn't find a pastebin service to host them.
I am running the latest xedit build 4.1.5c, when I load all my mods I get stuff like
and no pop-up message.
As for the other error, since xedit is still logging this (just as a warning) I think that it's either a problem with the mod file (I cleaned it so maybe somehow that's it) or xedit, so I'll move to the xedit discord about it
