Flight Report Data not appearing and causing CTD after airplane crash

[Blanjipan]

Hi, so recently I have been experiencing a very obnoxious bug that I have seen in modded 1.0.5 and unmodded 1.1.1

The first time I experienced the bug was in 1.0.5 where I built a (heavily modded) plane that I was impressed of. I took it out for a test and failed the landing, causing the plane to crash. The Flight Report screen popped up, but the grey box was empty and had no text. Pressing Escape would cause the words "Outcome: Catastrophic Failure!" to appear. I blamed it on the mods, but when I played 1.1.1 just today, I encountered this same bug, this time without any mods. The bug also disabled reverting flight, and if I switched ships and returned to the Space Center that way, it would cause a CTD.

If anyone knows how to fix this, that would be great.
