BP and everyday morning crashes

In my current project I use mix of C++ and BP. Almost everyday when I launch the editor it crashes and before doing anything constructive first I have to retract my steps with git and find out which BP from yesterday is causing this. For some reason they are saved in binary format which doesn’t help :frowning:
Seems like editor doesn’t like tinkering with what’s already used like altering enums or renaming BP variables and such.
Anyone has advice for me how to avoid this headache? I’d gladly go full C++ but BP is faster for experimenting and intellisense is so slow…
