Micro-patch, closer to a hotfix. Modifier issues have constituted over half the bugs that have been reported so I wanted to get this out ASAP.

Bugfixes:

• Saving/Loading for modifiers completely reworked. This should (hopefully) stop broken modifiers from saving, and if they are, they won't be loaded - just silently tossed into the ether. If you're still having modifier-related crashes after updating let me know.
  
• Fixed a bug that could occur when hovering over a choice that had no node attached.
