Music is still not playing in this build for me (it is fine in the stable build). Sound FX are fine, but after the first minute the music will cut out and not play until I hit F5 (which will then resume playing music until it stops again after a minute or two).
This is going to be a nightmare to make efficient! I wish you ever bit of good luck I can. It is one of my favorite things to do, set units on area patrol of the whole planet!
