First of all, here's my PC Specs so that you understand that it's NOT my pc:

Graphics Card: AMD R9 270 2GB
RAM: 8 Gigabytes
CPU: Intel Core i5-3470


It only happens in this map, not the default gm_fork, and basically what happens is that i get a red colored spammed error in the console that causes a lot of lag, the error is this:

GetSpriteAxes: Bad sprite type 1836216166

There's propably something wrong with the sprites you have placed in the map.
