Some Spawn Icons appear white.

Recentlly, I have been having problems with my Spawnicons, Alot of Spawn Icons show up as white squares in the spawnlist and the game will crash after a while/

Is There a way to fix this besides deleting the Garrysmod/Garrysmod Folder

Remove the Spwanicons folder. I did it once just for the fun of it. Well, to see if it would actually remove them. It made me reload them all again. But they where back to normal.

Give that a try.
