Skill Bug On the off chance that you still don't know what the skill bug is about (unlikely...), the game is letting you choose skills before you have the points for them. I.e. Three skills available at 29 points, but only two function. Player Collision Friendly players get stuck if they move through eachother too closely. They can, of course, move apart if they move in opposite directions. Someone claimed it's been around since 2.25.
You get stuck INSIDE the walls that you are building and standing on if you're touching a teammate with soft collision. emp_unstuck, where the fuck is it guys?
