Happened to me 30 minutes ago.
■■■■ priests.
The dungeon afterwards was really weird, only me and a hopolite were at the start of the dungeon so we started to work our way to the boss which worked surprisingly well. The entire time 2 of our party members, which I haven’t even seen in person, were shown in the boss room on the map. I found this odd since there wasn’t a single monster already cleared so I assumed that this was a bug.
Eventually me and that brave spearmaiden arrived at the boss, and to my surprise the 2 mystery party members, a barbarian and a sorcerer, were already fighting it and had it at like 10% hp.
Anyone else experienced party members that seemingly instantly teleport to the boss?
