When you jump at the exact time you walk up a ledge, it launches you straight up instead of forward. The animations while walking up and down the ledge have been smoothed, but the bug still persists 🙁
It has been there before the animgraph Beta as well (since CS2 came out). Unfortunately I dont have a 100% consistent way to reproduce it every time, since i cant get the timing 100% right. It works on every curb on Nuke and I'm certain that this also happens on other ledges around every map.
