With the wiggle, can you post a savegame where I can repro that? Ships rotate when they are going to move to a new location, but they need to not rotate if their destination is under a certain distance away. I tried to fix that, but didn't have a save to replicate the issue with, and apparently did not fix it.
For the ship overlap, is that something in old savegames or new ones? In old ones where we resized ships, that's just an unfortunate aspect of us changing the size of things. If it's happening in new savegames (ones since all the ship visuals were finished), then that's something I'd love to see a save of, too.
Turrets pointing at what they are shooting at would be nice, it's good to throw on mantis for at some point.
The ships decollision logic is something that can only run but so fast, although I'm not sure why the ships are hanging around THAT slowly unless there's really a ton going on. It's throttled by the galaxy activity amount to some extent, so the fuller and larger the galaxy and more stuff moving around, the more likely it will take more than the usual half second. Forcefields themselves shouldn't ever be moving away from their position unless they're overlapping something stationary or a fleet leader; though I think they're even supposed to pre-empt fleet leaders, IIRC. Repro cases for those things would also be welcome.
These are great things for mantis if you don't mind; mainly because I need to finish the tutorial framework and the other critical usability issues, and then circle around to things like this. So it may be a month or two before I tackle this and I don't want to forget. But if something is hindering usability, then that tends to jump up the chain of importance (like forcefields moving).
Thanks!
