Crash on inserter drop position set (on renai transportation inserter):
Just clicked one section on drop position and got the crash

The mod Cursed Programable Inserters (0.6.5) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event Cursed-PI::on_gui_click (ID 1)
Cursed-PI/control.lua:28: attempt to index field 'values' (a nil value)
stack traceback:
Cursed-PI/control.lua:28: in function <Cursed-PI/control.lua:17>

I'm testing with renai, all inserters are working fine to me, but i'll add a condition, i'm forcing to make 'values' nil, and it should be fixed.
Thanks for report!
