I started a new game today to test 1.13, and I've confirmed that the repair bay issue and the turrent problem. Repair bay seems to have the same problem as the Novalith (I haven't reconfirmed this, but it wasn't in the change log, so I assume it is still non-functional) where you could research the tech yet still have it say you need one point in the required research. Sense it makes little sense to have both the repair bay and the repair ability require the same tech, just removing the requirement on the repair ability should fix the problem.
Turrent issue has me baffled, I wasn't aware structures had attack behavior, but if turrents do, thats most likely the problem. Some goes for Novalith, I have no idea whats wrong there.
1. Interdictor's designate targets ability has several issues. First, on the research tree, the prerequesite arrow for it shoots off the enforcer and is incorrectly placed in the level 6 column instead of the level 7 requied. Also, for some reason the ISD research prerequesite arrow starts from the interdictor... wouldn't it make more sense if ISD and designate targets were switched around. Also, after researching designate targets, neither enforcer nor interdictor gets the ability, so it must have the same issue that sabatoge reactor and cluster missiles used to have (they work great now). My two cents, designate targets would be a great ability for enforcer as interdictor is bloated with abilities already.
2. I'm pleased to say quick start works fine now, except it spawns TEC scouts instead of Corellion gunships. But they are virtually the same thing, so I'd put this at the bottom of the priorities list.
3. Lack of lancer shields, and more importantly mitigation, leaves me concerned. I haven't had a big enough battle yet, but in a large fleet battle they could drop like flies without it. I'd break with the star wars universe and say they were modified with a small shield generator (even 100 points would work).
1. Quick start
2. Build icons
3. Balance issues seemed resolved, no major game breakers
