Access Violation with a particular order or plugins in a merge

[CrankyCat]

My original load order of merged plugins worked without an issue but upon rebuilding the merge with a different load order I get an access violation. I deleted the merge configuration but that didn't matter. When I changed the plugins to use the original load order again it worked. I'm not sure which one is the culprit.

So this worked:

Renumbering Conflicting FormIDs
Renumbering FormIDs in Power Conduits and Pylons Overhaul - SKE.esp
Renumbering FormIDs in Passthrough.esp
Renumbering FormIDs in PowerLinePhysics.esp
Renumbering FormIDs in LongerPowerLines3x.esp
Renumbering FormIDs in TimerPowerSwitch.esp
Renumbering FormIDs in SolarPower.esp
Renumbering FormIDs in MakeshiftBattery.esp
Renumbering FormIDs in VerticalConduits.esp
Renumbering FormIDs in NDLConduits.esp
Renumbering FormIDs in ConduitFloors.esp

This failed:
