And it's not over.... I was trying to make some planes fight each other, but a) they wouldn't show up in Vessel Switcher b) wouldn't attack each other anyway c) When they did show up together, it crashed when I tried to swap to the other vessel.This is probably a bug rather than my screwing up due to install issues (due to it kinda maybe working earlier).
The first time I spotted the vanishing from VS was after I put rover wheels on my planes to more easily move the bloody things off the runway. I initially thought that it was due to them being thought of as rovers, but that doesn't make sense. I swapped out wheels, did it several times, then I went 'screw this' and took control of a plane myself to try and strafe the one on the ground because it was refusing to take off. I got really close and then the other plane showed up and I tried to swap to it when the crash happened. There was some simulation slow down (yellow timer numbers) throughout it, but I don't see how that would interrupt the pilot AI and VS.

There's the crash report's zip file. I'm assuming this is what you mean by 'KSP.log'?
