nCloth Reference bug

Anyone care to test a interested bug?

We work with referenced nCloth rigs. However i noticed we can not unload them after we make nConstraints on the referenced rig.

Reference this rig(nCloth_Rig_RefTest) into a new scene
Select some point on the plane.
Make a transform constraint.

Now if you try to unload the reference.
maya will crash.

Windows 7 64 bit
Maya 2013 sp1 and sp2

Our only workarounds for this are to load the scene with all referenced unloaded. Change the path then reload the references.
Or edit the ascii file by hand.

Yes, I have had to resort to the ascii edit method many times for the same reason.

Another annoying thing with nCloth references is that any connections you make to the nucleus in the master scene (like your constraint for example) create reference edits with a specific nucleus input index. So if you later modify the nCloth in the original file (the one that is being referenced), that index may get taken, so now the reference edit (and therefore your constraint) will fail when you update the reference.

Thanks for confirming.

I've worried about that. But so far we have been able to avoid most of that. Because we script our sim rigs.

It does make me think more about how best to rebuild Simulation scenes. Simulation scene tend to the most clustered with ticks to make everything work. And you end up just thinking. Am i just recreating what Maya does?
