@kusurusu If you remove packs that saves have been saved with, there's always a risk with that.

I think there's even a warning in the game for this.

@crinrictWhat about library/gallery households feat. familiars (amongst other things)? If you try to place/play them without ROM you'll get an neverending loading screen.

I wish Icould provide you the gallery sim which caused this bug but I can't find him anymore (household's name was just "wizard" afaik)

[crinrict]

@kusurusu I assume the familiar doesn't show in the gallery so you don't really know that there is one ?

I think that should probably be blocked if you don't have the pack.

I'll see what info I can get.

[crinrict]

@kusurusu Are you still having issues with this ?

[kusurusu]

familiar tracker issue still exists as of v1.24 (console upload)/1.62 (pc base game download) - game keeps on spawning LE entires instead of while trying to load household
