A few bugs a noticed in 0.2

Hi,
Been playing DoTH since launch, have about 7 days played on my warrior, and been mapping a lot recently. Notice a few bugs that I would like to share or talk about, not sure if they are bugs, but they feel like it.
EDIT: got recommended to move this post from feedback to bug reports, more fitting to put it here.

1) I started Arbiter and noticed that I had the wrong equipment, you can't obviously leave during a boss fight, but i whiped like 8 times? but couldn't leave. I ended up powering through and finishing him, but did I do something wrong here? Are you not able to leave this fight whenever you choose? Like, I get you're riding the platform down to him, but it should still be an opinion, right?
EDIT: read that this is a known issue that you cant leave boss-fights.

2) Noticed when mapping when you get a slow effect on you that it persists to be active even though it has passed and there are no visible debuffs on you. I learned to solve this by porting in and out of the map. Still, with the self-fix, it's enjoying when the map is juiced and there is little room for error when surrounded.

3) Yesterday i opened 2 strongboxes in two different maps that had the "freeze when open" modifier on them, which is cool since I'm running freeze immune charm and it procs instant. But on those two occasions, my character just froze and wasn't able to do anything—not move, not press anything; he just stood there and got surrounded instantly. I had to log out to the character screen and log back in to be able to move.

Anyway, would like to hear if anyone else has experienced any of these. The game is good, still needs a lot of work, but I'm here for it.
