Few Bugs i've Encountered recently

Strongbox freeze - Opened a Strongbox, char freezes in place, can't use any skills, relogging didnt help. Good thing I have 2 chars, so I just log on my 2nd one and do the map.

Crow Bell boss (or whatever his name is, the one on Blooming Fields) - If you nuke his HP too fast before he gets the Bell, he becomes invincible and unkillable.

Simulacrum - one time, a mob spawned in the previous zone I completed and I couldnt clear the wave, lost the simulacrum.
