I first noticed this bug when night grom opened up, every great once in a while specially if I was hitting a big gap like a stair set I noticed the animation of my ollie or flip trick looked really snappy and un natural but I couldn't put my finger on why. Soon after S4 dropped I noticed it again but happening constantly so with closer inspection I noticed my characters leading foot clip through the board but its not just that, it appears there is a delay in the foot dragging up the board causing the synchronization between foot drag and board lift to become out of sync resulting in the foot clipping through and an ugly snappy looking animation.
The interesting thing about this bug is that I have never been able to replicate it on flat ground, it only happens when popping close to or interacting with an obstacle and also happens when going switch or fakie.
In the clips attached each one will have the normal speed so you can see how snappy it looks and then the close up in slow motion.
This bug has been driving me nuts!! and a lot of other players in the realistic community are getting really frustrated as well specially those of us who pay close attention to detail in making footage that looks good.
