I don't know for sure, but I've seen people say they had this glitch too, and that there should be an invisible guy on the level which you can kill to fix it, and if your on 25$ then you can see the guy and kill him since he's only supposed to spawn next to the water cooler when its on 25$ (and maybe 15$ I'm not sure since I only play 25$) but for some reason its on 8$
