Hi Pinchinator13,
I was able to locate your crash in our Crash Reporter. Your crash is a known issue (the JIRA for same, for reference, is UE-15553) and is apparently related to compiling after a blueprint dispatched event. It has been fixed, however I do not know at this time if the fix will make it into the 4.8 release.
As such, what you can try is this:
Make a copy of your project, and
download the most recent 4.8 preview.Delete from your Engine folder: DDC
Delete from your Project folder:
Intermediate, Saved, Binary and DDC.Restart your computer.
Then migrate
your project to a new blank project in
the most recent 4.8 preview.
If it continues to crash, please provide fresh logs.
Thanks and good luck!
