All avatars derived from IMVU's original Male and Female avatars have a limitation in which some actions and stances which are embedded in rooms do not perform as supposed to. This is because the deafault ID for avatar actions and stances in rooms and locked rooms is either 80 or 191, and since these rooms do not recongnize a different avatar ID number as a regular avatar, the derived avatar cannot perform in some situations as the regular one does.

This issue has been reported to IMVU through email and a post at the IMVU Bugs forum. To read more about this issue and to keep yourself updated on this, please visit the following link:

Avatar Derivation Bug

I have fully tested and retested my derived avatars in different locked rooms, rooms, and with poses and furniture, and the only limitation to this issue seems to be on some (not all) actions and stances embedded on certain rooms.

Since this is an IMVU-related problem, you can also report this issue directly to IMVU so they can work a fix to this. You can do so by filling a support ticket HERE.
