Stop RTR droids from dropping group and accepting orders

[stuart]

This changes the behaviour of retreating droids. They retain their group but will ignore most orders except hold until they are repaired.

#2330

I think it's a good choice.
Units under commander also ignore all orders (even HOLD POSITION), so the only way to make them do something else, is to remove them from Commander's group, which is similar to here (once you fix your isRetreating).

While it seemed to me a good fix, MP people aren't excited about this, because that prevent manual intervention in critical situations.
I suggest we wait for a more fine-grained solution

[stuart]

I have been playing single player with this fix, and it works as intended with units rejoining after being repaired. I can see why you would not always want that behaviour especially in MP. By more fine-grained solution do you have anything in mind?

[gantsevdenis]

Absolutely nothing :(
I have a solution, which would be to apply your fix for Campaign only, but given the fact that this bug was initially reported by MP community, that doesn't help much
