Ah OK. Remarks remain the same, just in case a dev can do something useful here.
sideEnemy is not a "basic" side (we can't create center or join a group with that) but it's weird a player as renegade stays in his original group.

Hey headydone
Not sure Razazel will answer. All you mentioned above came from my own remarks. Sorry if you feel disappointed, but no dev did anything for that since... 2016.

Still assigned to None....

This feature request is not for chat but radio. Actually, the voice radio is just filtered by channel, without consideration about range, jamming, ground masks... You can't scan, point at direction, reveal radio emitters.
The reason why EH or MEH could enable some scripts when AIs/players use their radio.
Examples:

• if leader player is separate from his group/ other players by a hill, radio can be blocked or dimmed, (except if backpack is a radio but this can be scripted in EH code);
• if an AI/player emits within a short distance from enemy, reveal it to enemy;
• find azimuth of emitting unit;
• script radio volume for what you want...

No this occurred (twice at least) on native mission (Canisy or Quibou Dangy one), just playing without any mod other than the DLC, on hosted LAN sever, one player only.
I guess you have something for performance optimization with your own simulation switch tool. This (these) unit(s) should be animated or hidden, or not spawned. Something like that.

Any news about that?

In Diag_captureSlowFrame:
**biki warns: "Only available in Diagnostic/Profiling branch(es)."

I think this issue is due to lag in 3den due to too many running scripts. So the config viewer can't open and a zero divisor occurs by some lost variables.

No interest?

Seems to be the case also for :
13:46:49 Warning Message: No entry 'bin\config.bin/CfgMagazines.US85_38x_M151'.

Tested with "any member of the group" :
All mission.sqm (pboed or not) have an emptyDetector (trigger) set with :
activationByOwner="MEMBER";
and a link (of course) type = "TriggerOwner"; between items referring of the group and the trigger. Fine!

This bug is not corrected.

This command is still broken. See KK's comment (2013!)

Ok, seems to impact also mods and DLCs.

This bug seems to be specific to Vanilla 8 unit weapons squads (BLU,RED,GREEN). I tested with 8 unit recon squads or Western Sahara 8 unit squad and I didn't see that.

Yes. That's what reproducibility: "always" means. It takes 1 min (but 2 PC or sessions) for testing with 2 players.
