Got this error message since yesterday. So we start try to reproduce this error starting arma 3 server vanilla. Without using any mod and also launching bis official mission ( headhunters ).
This error is spammed in RPT very heavy with many players ( 1,5 mb rpt with 2 hours play ) {F22500}
1)Start server
2)start random mission
3)launch a granade near your feet hurting yourself
( there are sure other way to reproduce this error but didn't test all others because when we start a mission this error is reproduced also in base without enemy contact and without fire/launch granade, so it's not the only way to reproduce it )
startup launch
In the rpt first there's a simple vas mission then at 0:50:25 we started an official bis mission ( headhunters )
