After an update, I started getting these errors (see screenshot) after a hot reload (4.15.1):
And in output log I see a lot of:
LogLinker:Error: BPGC_ARCH_FOR_CDO_GameSaveProLibrary_5 has an inappropriate outermost, it was probably saved with a deprecated outer (file: …/…/…/…/…/…/HELM/depot/TheSoulkeeperVR/Content/Blueprints/GameFlow/GameFlowBase.uasset)
What helps - close editor, recompile, open editor, recompile assets with errors to remove bad references.
