When I purchased my rank I waited a hour and nothing happened. I restarted Attack of the B-Team, reloaded the server, and still nothing happened. So maybe you have to do this every time you purchase something? I got the Tier 1 rank so you know what to give me. If you are the staff that fixes this Thanks so much!
Added your Tier 1 donor group to our 1.6 servers as you have it on our 1.7+ ones. Also added your kit as well. Enjoy!
