Okay, having played the newest beta a few days, I've seen some unusual things, but I'm not sure if they're bugs or not.

Playing as Drath, I complete the research for Defensive Meditation, but I cannot put the new component on any of my ship designs. It simply is not listed in the modules. Is there some restriction on the component I am unaware of?

Playing as Terrans, with the various warp bubble, fleet defensive modules and fleet offensive modules available, I try to design a 'command ship' for my fleet. However, I cannot put both offensive and defensive modules on the same ship. It seems they are both considered to be out of the same category of modules that allow only one per ship. This might be intentional, but I'm not sure. Additionally, an unarmed 'command ship' seems to always be targeted last in combat, regardless of what assistance it provides to any armed ships in the combat.

That's all for the moment. I'll see what else I can dig up.
