Absolutely nothing, or hundreds of our stand-ins would have issues :)
Absolutely nothing for the static kine state either, since for years we've
used compensation tricks changing that in unison to transform changes.

There are a lot of this with that can make bad things happen that are
borderline superstitious, but barring the odd bug here and there over the
years I've yet to see something that couldn't be explained by the user
misunderstanding or misusing features or properties.

Skinning and related properties in Soft are by far some of the most solid
and transparent out there.

 Out of curiosity, what bad things can happen from neutral poses on meshes
 and deformers? Skinning uses the global xfo for calculations so the neutral
 pose has no affect on that.

Taking a closer look, this is happening when I do the mesh binding.
The mesh shifts a bit right away (no need to go through the weights
editing step). Could it be related to transforms stored in the nulls
I'm using to deform the mesh? I don't see how something like this
could have been introduced, since all nulls were created by a
script... anyway, just exploring all the options.
Thanks for any help!

If your nulls have moved since you initially did the bind yes. Select 
the mesh Envelope  Reset Actor. Watch for a shift of one of the nulls. 
One probably has moved for some reason.


If your nulls are in a good place where you want them, you can use the 
current positions of the nulls for the bind pose but selecting all of 
them and doing a Envelope  Set Reference Pose.

Yes, also you may have inadvertently moved the 'center' (Button top right) of 
the skin element after the mute.
Reset the center if that the case.
Also, doing a “set reference poses” should  alleviate this, I think you must do 
it on the deformers (bone elements) and skin.
Save ur scene first;)

Check to see if you're using the 'approximated' envelope operator which skips

Transforms stored in the nulls?...do you mean neutral pose? if so remove
those, neutral pose is not meant for meshes or deformers as bad things can
happen.

Some TDs don't like them at all, but I find they work just fine on icon
controls.

Thanks a lot guys! Set Reference Pose fixed it. I'm not sure how the
pose could have changed, since as I said, these nulls are created by
a script, and they are cluster constrained to a mesh, so I would not
be able to move them. Anyway, the problem seems to be gone. Great!
One more new thing learned today 
:-) .
Cheers!
