I have a problem already and you have just given me the answer.

I have a .vmt file that makes my cross hair darker so it can actually be seen! It works on all other servers but not our normal maps server so I assume it is the "Pure" mode that is stopping it.

Is there a way that you can make it allowed or not?

Otherwise I played on there the other day with bots and I am pleased to say NO LAG! But we need to get them more populated as there are 0 on the fun server and 8 bots on the normal maps lol.
