I have started fight with current HL player limitation ... Before it became official, i need done some tests of the new technology i using for increase player limits ....
Untill all be done i sometime run old and new version of the server to track all posible errors. When the server will be tuned to handle that load i will rework the client, to be fully compatible with this new technology.
You will experience some problems with the client untill all be done.
Any issues you found, post please in to this thread:
