I’m investigating this further.
I’ve also notified Epic of this.
Hopefully the problem will be fixed soon.
Update:
Ok, I think I know what causes the problem.
Epic usually builds plugins against the base version (in this case 4.13.0) of the engine.
They have just rebuild it again using 4.13.0. Could anyone please check if the crashing still happens with the rebuild?
If it does, I have to let them know, and then they’ll rebuild the plugin with 4.13.1, which should fix the crashing.
Update 2:
They are now rebuilding it against 4.13.1, hopefully that will fix the crashing.
