1. With capital planet victory mode on, the normal AI doesn't seem to give a damn about their capital planet, happily letting you bombard it while they focus on some pointless asteroid elsewhere.
2. My Titan went into a magnetic storm (the one where abilities are disabled) and was stuck auto using Subjugation (Loyalist Corona). It couldn't cancel or complete the ability due to it being locked from the magnetic cloud, and it also wouldn't move or do anything else. I ended up scuttling and rebuilding it.
