Hi, I was hoping this bug would be fixed soon but it keeps happening. In various iClone projects, I try to change the position of some characters, but doing so sometimes causes unexpected situations. 
The funniest is that I select the character and move it but the clothes don't.

I have developed some of these projects in iClone 7 and assumed that the problem was related to exporting them to iClone 8, 
but I have completely redesigned the scene in iClone 8 and the same thing happens. 
I designed the characters in CC3 but I have edited them again in CC4 applying the facial profile CC4 plus and I have even reapplied the Skin Weights to the clothes and 
I have repeated the conformation step in CC4. I then transfer the character to iClone 8 and it seems to work fine. 
However, if I save the project and open it later, the problem repeats. The only way to fix it is to substitute the character again, sending it from CC4.

Today I have updated the iClone from the Reallusion Hub and I have 8.01.0531.1, I expected this problem to be corrected, but it still persists. 
I'also ve tried turning clothes physics on and off, but it doesn't fix the problem.

Yes, thanks Rampa. I assumed something like that would be related. I find it curious that it does not happen in iClone 7 but it does in 8. 
In any case, I have verified what you indicate. In the project panel, there is an option in Global Physics Settings, which I have configured in PhysXengine. 
Also Rigid Body and Soft Cloth are active, the latter with the Bake animation option selected. If I disable any of these options the behavior doesn't change.

However, switching the simulation to "Bullet Engine" and then back to the "PhysXEngine" fixes the problem. Thank you. I was looking a solution for this issue.
