Alright, so you think it’s bad when you spawn you have to wait two seconds for the textures to load, well, I’ve got it worse (only rarely!

I am a huge fan of the gun models, but boy do they look turribly turrible when the textures never load in correctly. Changing servers does not remedy the problem either. The only thing which I have found to fix the issue is by restarting the console completely. It’s only happened to me twice, so it’s not that big of a deal, and all I have to do is restart the console to fix it… but I believe it’s something that the developers may be able to fix! : )
I believe it’s caused when the console stays on for prolonged periods of time, at least this when it’s occurred both times. The console would be on for 5-10 hours and then the textures would fail to load.
