Two odd bugs (both builds):
1) Only joystick buttons 1 &2 as well as 7 & 6 seem to work in game. 3, 4, 5 (fire countermeasure, cycle secondary, next hostile) do NOT work at all. However, they *do* work in the settings, i.e. I can assign them normally.
2) One mission I tested (unfortunately not public) had another very odd bug. My view was 'flickering' around wildly (a bit like if in engine wash, but thousand times worse) all the time, making the mission unplayable. It is pretty much rotating 360° wildly around and around. If I switch to external view, this doesnt happen. The second I change back into cockpit view, it's there again. This has only happened with ONE mission (didn't happen with older builds), it does NOT matter which ship I choose, and is 100% reproducable.
Other than that, taylor's build seems a lot faster than Kazan's - the loading times are amazing, even though there still seems to be heavy memory issues in-game (though I'll have to say, they got a lot better.). I'll have to do more testing on this part to give you exact details.
