Weirdly enough, I noticed that I named one of my party members "Beatrice", but when I removed them from the party and the game tossed them to one side, they were spontaneously renamed to "Beatruce". This continuously happens whenever I remove them from the party, which is rather troublesome.
If you initially entered the name as Beatruce and changed it to Beatrice in the active party, it will revert when the character is removed unless you saved the party with the renamed character. If the game changed the name on its own, it's a bug. Otherwise it's just annoying.
Ah, it seems to have corrected itself x.x so it must have been some sort of weird cache thing; the name returned to normal after I left and came back to the tavern following a mission.
