what's the big mysterious one? mantis isn't working right now.
If you have Derelict SCP, try playing the mission "The Sting" in this build. Whatever is causing the mess that results has been introduced between Taylor's 0314 XT build and now.
Essentially:
-A Sobek can drive right into/through an Orion model (which the FSU says is a code problem).
-The Sobek totally ignores its waypoints, which work fine in every other build.
-Fighters are not properly accounted for, so even when all fighters are killed you're left with a positive count of 1 that screws up the rest of the mission.
I have a theory on the fighter problem: I think that the game is not counting kills of a remaining fighter from the first wave of the wing once the second has arrived. Thus, even when both waves have been killed you're left with the number remaining from the first wing once the second has shown up.
I'm sure these are larger bugs that will appear in multiple places given the things they affect, this just happens to be the mission I discovered them in and which they are glaringly obvious.
