3.1.1 b113 Double-Patching MC Fixtures

Attempting to double-patch a MC fixture in (2) separate universes and think I've discovered a bug -- The bug is not appearing with non-MC fixtures.

Channel 511 / Part 1 (in this case, a Chauvet MK3 Wash in Single Standard MC [129]) is patched at [UniverseA] / 1-129. Its' respective .cells appear as expected in patch.

Channel 511 / Part 2 is created (with the default type of Dimmer). All is good here.

Channel 511 / Part 2 type is changed to [any fixture type]. 511 / Part 1's .cells all disappear from patch.
