I just played a game on Hospital and I had some issues with the weapons.
For the first two or three rounds, the weapon selection UI didn’t show up at all. I had to blindly press keys before I got the gun I wanted.
Viewmodels were randomly invisible on a few occasions, but switching to another gun seemed to fix it.
For two rounds in a row, I spawned with no weapons at all. If I remember correctly, a lot of other players did as well, but not all of them.
