DynDOLOD.esp now only contains non overwritten Activators, Keyword, Quest and the persistent CELL 00000D74. The cell itself only contains one Tamriel_Sheson_Object and all the Minions and Firstborns. Checked for errors, none present.
Disabling scripts one at a time shows that removing either SHESON_DynDOLOD_Master.pex or SHESON_DynDOLOD_Firstborn.pex stops the crashes. Leaving just one of these two scripts is fine but it both are present the game will crash.
