The user's project is crashing during compilation of one of their character blueprints.
We have not been able to reproduce this issue in a clean project, as the repro steps are unknown outside of this particular project.
Deleting a variable and then recreating it allows you to compile the blueprint successfully one time, but then crashes on the second compile.
Found in 4.11 Preview 3.
1. Download the project located here: [Link Removed]
2. Open the I_MaleCharacter blueprint (Content->Characters->Male)
3. Compile the blueprint
Result: Editor Crashes
Expected: Blueprint would compile successfully
