[3.04? Update on our next patch]

Since the latest patch and/or the White March coming out, whenever I recruit Hiravias (may occur when recruiting other party members as well, I'm uncertain) I can no longer change my party. I can remove members, but when I try to add other party members, it doesn't work.

 

It can be fixed by disabling the auto-levelling of newly recruited party members, so It has something to do with that.

[Question about the Scouting ability.]

Ditto in this question. Logically, it would be perception, right? But I can't really find any information to confirm this.
