I'm not sure if I screwed up somehow, but the NPC that lets you swap party leaders on Highwind is missing, so I can't proceed on Tifa's and Cid's sidequests. I installed the mod with 7th Heaven, but I did make use of Black Chocobo save editor once in a while to add megalixirs, limit breaks and a Gold Chocobo (didn't want to go through all the trouble again).
There's also the cave (after the sleeping forest) sidequest that is very rough (field models come and go, field music keeps resetting between screens, among others), but the most prominent problem is that the entire party is already in the hideout prior to finding them, even though you can't swap to them.
I remember having tons of fun with the 1.4 version (noticing some oddities that have since been fixed), but somehow I've been hitting a few more rough edges with 1.5. In any case, it's still loads of fun, thank you very much for this mod!
