The issue has to do with the content is designed with a different endpoint than the base figure. With improvements and fixes to the conforming figure system, a few types of imprecise or erroneous states in third party content may cause that content to conform with issues. For example if content contains a combination of incorrectly saved joint origins and very tight parameter limits (0,-0), it may now behave unexpectedly. I am trying to find some details on it, but contact the Vendor. Most are aware that they have products constructed in this manner.
