commit from last FFNx
canary does introduce a new fix made by vertex about woa background you might want to have a look to align.
"Core: Fix desync background animation on the wind wall fields of `woa_*`"
This is the comment from vertex's
PR "Working on original FPS, 30 FULL FPS mod and 60 FULL FPS mod. For 60 fps it works only with the 60fps flevel fix activated"
Note: opening menu doesn't break background animation anymore.
Also, after a battle... the animation is properly resetted.
