When i am attacking someone with my melee and i get killed at the same time, i try the respawn button and it works, but when i respawn, i cant attack anymore, it looks like the left click is blocked (shoot, using melee weapons, punching), i still can use the iventory with the left click, i think its because the delay for the next time you attack dont get a reset when you respawn.
Also it happens on the experimental too.
