Script sources must be loaded in the following order:
- Creation Kit scripts (Scripts.zip)
- SKSE scripts
- Enderal scripts (ScriptsEnderal.zip)

Enderal uses vanilla SE sScriptSourceFolder location (Data\Source\Scripts), while SKSE follows the old scheme (Data\Scripts\Source). Reorder script locations in all three components to be the same, either Source\Scripts, or Scripts\Source.
