Weird reference-related compile error on reloading editor until you re-check out and save function library and then the calling blueprint

[anonymous_user_8f043ea0]

Oh, and to help you narrow it down – I also get errors on trying to save, before compilation has been successful (i.e. before I check out and recompile the library class and then go back and recompile the character class).

I attach screenshots of the save errors.
