Looks like #1 was fixed in today's dev-build :)

Added another simple repro mission (A3B_Gun_Fire_Distance.zip). Just engage the enemies on the other side of the valley and listen. All you can hear is the bullet cracks and some ricochets in the rocks/ground.

Sorry for catching this late astaroth, I haven't played much during the summer...
Played a few rounds MP but did not experienced above mention issue.

Here are the crasdumps...

Are you sure it works in MP? I mean... does it add a new playable slot in the lobby for the created units? I'm on stable and cant get it to work here.

@dippysea: Do you mean in SP? Can you be a bit more specific? Just tried and it does not work in MP.

@devs: Any acknowledgement or possible workaround for this issue?
