I get this error every time I try to create a Multipatch using version 0.37p:

Can't call method "Parameters" on an undefined value at script/tes3cmd line 290

When using version 0.37q I get:

Can't call method "Parameters" on an undefined value at script/tes3cmd line 304

I honestly have no clue what's causing this, I would appreciate any help as this has been driving me nuts since I woke up this morning (it was working perfectly yesterday).
