No, I don't think so. I even re-rigged the models again from my saved flipped model. Same result, all control bones were hidden and the leg mesh wouldn't move after I unhid the control bones after rigging. It worked perfectly the first time I did it. But, after I opened the project again, the control bones were hidden. I know I didn't save the project or model like this.
Maybe it's an TSM2 install problem?
