Like clearly announced in the
releases notes, the target omega code was recently changed to match the one of the latest viewer-development code, and I was asking for feedback about it. Your issue is most likely related with these changes...
The good news is that the changes can be reverted via debug settings. First try setting UseNewTargetOmegaCode to FALSE, and see if it cures your issue. If not, reset it to TRUE and set IgnoreJointInfo to FALSE. If still affected by the problem, then set again UseNewTargetOmegaCode to FALSE (so that both UseNewTargetOmegaCode and IgnoreJointInfo are FALSE).
Let me know which settings combination works best for you.
