Under certain circumstances simulation changes on server on groups which have dynamic simulation enabled also changes simulation on client, which was not the case until recently (when this changed is unknown).
Normally when a AI unit was disabled by dynamic simulation on server side there was no change of simulation on client side (simulationEnabled kept unchanged), the only effect on unit on client side was that it for examkple would walk on same place.
However this issue only occurs under certain circumstances and is not always reproduceable, which indicates that its indeed a bug and not a intended behaviour change.
One situation it seems always reproduceable is with newly created groups, a reliable way to reproduce it is added below.
Changing triggerSimulationEnabled status on server side might also trigger a change of simulationEnabled on client side sometimes, but thats not fore sure at this time.
