notes:

Sometimes (3/5), when exiting -­game -­vr with the OSVR running, UE4 will crash.

my notes: possibly related to https://github.com/OSVR/OSVR-Unreal/issues/86 and https://github.com/OSVR/OSVR-Unreal/issues/87

I cannot reproduce this after https://github.com/OSVR/OSVR-Unreal/issues/97 but I had trouble reproducing it before then as well. Tentatively marking this as solved.
