kidx, here is some good advice:
when asking a question you need three parts
1. Your question
2. Background information to problem
3. What you have tried so far to fix it
You skipped over #2 when asking your question. It is next to impossible to diagnose and help you if we don't have any context with which to frame your question. How do I know when you are entering the ge_allowradar command? Were you using dedicated or listen server? What game modes were you playing?
ALL of that information was missing, making our answers almost meaningless to you in the end.
