KF Serious compatibility problem of few mutators and ServerPerks

I encountered this problem when I was writing new version of AdminControlv2. I finished this new version, tested it and give it public access. But after that, many people using it on their servers with ServerPerks noticed serious bug - some random players didnt received perks to select list and trader list is empty. After some time I met this bug in the new versions of ScrnBalance and in one more mutators. One man supposed that this issue is related to fast connection of that players and lowering MaxClientRate can help. Maybe it helps in some cases, but mostly lowering MaxClientRate is uacceptable due to productiveness problems. As I can see, something happens with ClientPerkRepLink that is responsible for trader list, but I didnt find out more. This problem doesnt allow to properly use AdminControlv2 and other important mutators. I wanted to make thread for AdminControlv2 on tripwire forums but I cant do this until this bug isnt fixed. So I asking for help of experienced coders, maybe someone can find out something about this issue.
