Report to https://www.curseforge.com/minecraft/mc-mods/rslargepatterns .

The latest update has changed things and every addon will need an update to work with it.

But I updated the addon too

You might have updated the RSaddons mod. You did not update rslargepatterns (as there is no update for that).

Oh I see, thanks anyway :D
