    I don't know what it is all about but still it is something related to CRASH ON UMBRA::TILETRAVERSETREE::INIT<UMBRA::STARTCELLFINDER> WHEN ENTERING PLAY MODE OR SELECTING CAMERA GAMEOBJECT. You have to go for https://assignmentman.co.uk/ now or sooner this week. Maybe if you have any idea about it then let me know what it is.
