Took me awhile—honestly, haven't been playing much CK2 and have touched GOT even less, but I've finally gotten around to updating this. v0.7 is now available in the first post. Works with 2.2, no changes from the previous version.
Alright, figured out the issue. There was a bracket missing in the zz_casus belli file. Loaded it up as Stannis again and the wars stuck around. You can find a new download on the first page, sorry for those who might've downloaded the borked file!
