No, he launched from Steam as usual (without elevating it to administrator status). That seems to contrary to what you wrote.. or it means that Steam gets elevated rights automatically from somewhere. Even if the problem is not anymore considered part of ACRE it can still affect users of ACRE. Might not be a bad idea to keep that information available for new users.
Moving on, we encountered some slightly odd issues while testing it today with three players. Direct speech seemed to work OK at all times, but radios had some seemingly random issues along the lines of
- A and C can communicate with B but not with each other
- A can hear C but C cannot hear A and neither one hears B, but B hears both A and C.
These were observed regardless of distance, within direct speech range. I'm not quite sure but I think these issues may have appeared and disappeared as people got killed and then respawned. We were playing WLA. I was wondering that maybe the respawn script interfered with ACRE2? I don't at least recall ever having similar issues in ACRE in ArmA 2. Any thoughts?
