Blurred scope.

1-st attach.

 After I respawned, I discovered that the crosshair had become very blurry and I couldn't see anything through it, including enemies. After I died, everything returned to normal, so I don't know what caused this bug.

Stuck in the spawn.

2-d attach.

 After the match started and after the intro, I got stuck on the spawn point and couldn't move. In this case, everything was fixed after respawning as well.

Disappeared weapon.

3-d, 4-th attach.

This bug is much more annoying because it cannot be fixed by simply respawning. Most likely, the only solution is to reconnect to the server. I encountered it after I alt-tabbed to Discord and turned off the stream. When I switched back to the game, my weapon was gone. I tried to respawn, but the situation only got worse — even my hands were gone.
