There are word-wrap issues with weapons. That was the only one I noticed.Edit: It seems the ones that are not translated so far are hard Images that cannot be touched by AI TL. The translated text though is alright for AI TL standards. Have yet to see wordwrap issues.
It's not that bad. It's pretty obvious as you play when something is going to affect the other character, and if it isn't, the game will just tell you that it will.Edit2: Yep the Cross effect not getting translated is a pain in the ass, since it heavily impacts gameplay and gives hints/ how the story will go.
