I have seen a few similar issues raised but the users were not able to repro them.
We have a 100% reproducable crash when we do the following:
- Open our map which has a matinee in it
- Duplicate this matinee
- Edit the duplicated matinee (doesn’t seem to matter what we edit)
- Save map and close editor
- Reload editor and open map - crash on load
The crash occurs when creating some InterpData which is editor only code, thus loading the map in game is fine.
I have a video and two map files I can provide to show the crash, and I can repro using this content in the base engine 4.2.0. I couldn’t attach them here due to size/file type restrictions.
This crash is 100% for us and repros on multiple machines.
The assert is: Assertion failed: !Obj->HasAnyFlags(RF_NeedLoad|RF_NeedPostLoad|RF_ClassDefaultObject) [File:D:\BuildFarm\buildmachine_++depot+UE4-Releases+4.2\Engine\Source\Runtime\CoreUObject\Private\UObject\UObjectGlobals.cpp] [Line: 1751]
I’ve attached an image of our matinee in the matinee editor.
