Zbrush Subtool Woes

I've got my Zbrush up to date and working with subtools since my last post, and it has been working fine to use subtools until today.
Today, each time I try to work with a new subtool in my set, I get this message:

INTERNAL ERROR .\list.cpp Line:143
Locked main mem in list-out
Object:

Please email use at [email=support@pixologic.com]support@pixologic.com[/email] with the information you see in this dialog. Click 'OK' to exit Zbrush or 'Cancel' to continue.

(pressing ok of course causes me to exit Zbrush and hitting Cancel actually just ends up crashing Zbrush)

Let me explain completely what I'm doing. I have a two part boot and I want to add a top to it. I append a new sphere (the premade one that I have loaded in my tools) in the subtool menu. Next, I select the new sphere on my subtool menu so it is the one being editted, and next I drop down to the Deformation menu to use the Offset on the Y axis so I can move my sphere down in a straight line. This is where I get the message, just after I've moved the Offset slider in the deformation menu to move my newly appended sphere. I don't see why this should be happening.
I see it says to email pixologic, which I'm fully willing to do, but I don't see why trying to move the shape should be a problem I need to email pixologic over (they must be busy!!) and I was honestly hoping someone could easily tell me what I'm doing wrong. I've used this many subtools in a set with no errors before, but I've never tried to use the deformation drop down items on the subtools until today. Are the deformation menu inputs not able to be used on subtools? What's odd is that when I appended my FIRST subtool of this set, I was able to move it using the offset under deformation, the very thing that is crashing now.
Is there another way to move my pieces in a straight line on the Y axis? The only other way I've found is by holding down shift while in move mode, but that only moves it left to right, not up and down. **I NEED my tools to stay alligned to eachother.**

-k I did end up emailing support after writting this, but I'm still looking for a work around, so help is appreciated.

Like this:

After you've appended your new subtool, sculpt the appended tool's surface slightly and then hit undo. You'll now find that you can deform your tool without ZBrush crashing.

I'm guessing that any change (other than a deformation) to the appended subtool will fix whatever it is that's making ZBrush crash when using the deform functions.

i get the same dam thing theres a zsubtool plugin that fixes it ill look for it.

also when i have multi objects merged the sculpty maker wont make a sculpty says to many vertical.

what are you using to get the multible objects into a sculpty?

I don't know of any exporter that can export it as a single object for Second Life. You'll probably just have to export each peice seperately and reassemble it in world. That's the only way I know of, but if someone knows something different, I guess they will chime in.
