Mission Planner Swarm SITL down

Both ArduCopter and ArduPlane swarm are down, looks like the update on July 21st killed it. I was running a 5 drone swarm no problem, but now the arducopter instances only stay open for ~100ms. The following command ( 5 instances) is being run and arducopter.exe returns the help menu which causes the instance to close.

ArduCopter.exe --defaults “C:\Users\michael\Documents\Mission Planner\sitl\default_params/copter.parm,identity.parm” -P SERIAL0_PROTOCOL=2 -P SERIAL1_PROTOCOL=2 -M+ -s1 --home 34.9494742,-106.5370951,1650.90620479358,0 --instance 0 --serial0 tcp:0 -P SYSID_THISMAV=1

Each instance does have a different SYSID_THISMAV number.

I did find a work around by using a version of arducopter from early July which works for my needs but has some weirdness like wanting accel/compass cals and giving AHRS errors. I disabled the start up checks to get around this but still get AHRS errors.

Latest Beta Mission Planner, swarm is working with single and multi link, stable and dev AP version…
