Physics loop in dark room
I was testing some light entities in the dark room under the stairs. A wooden pallet started orbiting the center of the room at a fixed speed. I tried to prop-remove it, but the command failed. My client's frame rate dropped to 4 fps instantly.
xX_PropKiller_Xx: i saw this last week on a different map. its the engine failing to resolve collisions.
user9928: did you check your console? usually shows a huge stack trace

Vibrating Prop_Physics
The prop_physics wouldn't stop vibrating. It didn't make a sound. Just a constant shake until the client froze.
GModFan: happens when you spawn stuff too close to the navmesh sometimes
MODERATE
Gray Shadow Entity
Saw a shadow entity near the spawn. It looked like a player model but the textures were just gray void.
