Alright, if you've been in the chatroom, you may know this.
Recently, I've decided to get on with the story of Sylestia. I'm on Garden of the Magnates (is that how you spell it? idk) and did the little event where an ally gets hauled off by a Corrupted Qitari and rider. I thought it was nothing, just another little event. No big fight or anything.
Onto the actual bug.
So after a few fights, I explored the area, and got the normal "you see something. you can't tell what it is" screen. When I decided to inspect it, after the normal interaction with Jinxie and everything, I got the same Corrupted Qitari from earlier. Five stars. It was definitely a boss- but in a normal encounter. I failed to beat it (due to lack of planning on my own part lol), and tried again after my pets healed while retelling the whole thing to the chatroom. This time it was a regular "You have encountered an enemy!" screen, but when I entered the fight, it was the Qitari again. After a second butt-kicking, I tried again a few minutes ago, and there it was again.
I checked out someone else's playthrough of the story, and they didn't ever mention the thing.
I'm not sure if defeating it will fix the bug (BECAUSE IT'S REALLY TOUGH AND MY PETS ARE UNDERLEVELED :,) ), but even if it does, I don't think bosses pop up in regular encounter screens. Please look into this. Thanks!

Update:
I managed to beat it, and the story continued on. So i guess it was just an issue with the pre-battle screens? Idk, this may have just been a minor bug. Sorry if it ended up being nothing ;^^

I'm not sure.

I can try to see if I can find anything, but it might not be possible now that you've moved on since I won't be able to reference what specific step you were on.

I'll see if I notice anything though. Thank you for letting me know.
