LDCad Flex object bug report

[Orion Pobursky]

I'm getting an odd error when I edit my custom flex axle  in a certain way. Attached is a test case file.

Step to reproduce:
- Open test.ldr
- Enter nested mode
- Click on either control point
- Hit Ctrl-R to enter rotation
- Enter an arbitrary number into the rotation field
- Hit accept and notice odd output
