Crash/conflict with Mighty Architect

[Syndaryl]

Description of the issue:

After composing a structure in Mighty Architect, I save it to a schematic, and Minecraft crashes - it manages to touch the file (create it on disk) but no content is written to it.

I'm creating an issue here because the crash report suggests that IE does somethingy in the middle to do with wiring, even though no wiring is present on my superflat world, and crashes.

(It seems to choke when Mighty Architect triggers the feature template handler - this triggers the Wire Template Helper in IE, and then it tosses its cookies with a No Net Handler found for dimension minecraft:overworld.)

Recreation Steps:

1. Press G to open the mighty architect composer
2. Pick 1, 2, 3, or 4, as your fancy takes you (building style)
3. right click on the ground somewhere
4. right click on the ground somewhere else nearby
5. scrollwheel up once or twice just to add a few floors (optional)
6. press G to go back into the mighty architect menu
7. press F to finish composing and go to decoration phase
8. No need to actually do any decorating, just press G again to go back into the mighty architect menu
9. Press S to save as schematic
10. Pick some random name and press the Save Schematic button
11. Crash

As noted on the MA issue, if I uninstall IE, Mighty Architect works fine.
