Freeze bug

I have a thawing charm (immunity to freeze)

I opened a strongbox which freezes me on opening.

I got frozen, i saw that thawing charm triggered but im still frozen.

I got frozen for like 10 seconds until i was dead.

I respawned in the checkpoint still frozen for infinite time.

I had to relogin to stop being frozen. That's not a network issue because i was able to see chat going, my ping was ok and everything worked fine.
