Bend settings changed when opening model

[BBruce7815 2k]

This is an issue I found in the latest update of Modelbench (Beta 0.3.1 as of now), and it goes like this:
Every time I open a model, all of the parts change the "lock to bent half" option to checked, how did I manage to find out?
1st: Open a model that has parts connected to both the bent and not-bent half of another part.
2nd: Save the model
3rd: Open the model in MI and bend said parts.
I found out after saving a model with a part that had the option unchecked, then closing MB, launching it again, and loading the same model, just to see the option checked.

Small bug, but a pretty destructive one imo

(Tested in 2 different models to make sure it was a bug in the program and not the model itself)
