Game crash on missing font

I was playing the latest version of the game and was about 2/3 of the way through the level when the game crashed. The error it gave on crashing is shown below. It looks like it cannot find the bluehighway font, but that doesn't make sense as it was running for quite some time before that just fine. I had opened a creature stats window at one point during the game and I know there is the potential for a crash when the creature whose stats window is displayed gets killed. I don't think this is what caused the crash but I will try to refrain from using the creature stats window in the mean time to verify that the crash is not in that code.
