Okay, so after trying everything from polish to drilling to floor wax to try and keep the tabs on Menasor's shoulders in I took the plunge and did the one and only definitive fix. It is pretty invasive involving a Prime, preferably battle Core and taking sections apart on both. I love the end result though. It makes a world of difference. And, honestly, not as hard as it sounds. I show what I did pretty much step by step and how, in the end, I still have two perfectly fine figures.
