If not,should we add new patch block into run'n gun level category?

We might do that. We didn't touch the Run n Gun ILs yet, because we were focusing on the Main Boards. So you mean something like, No OoB / OoB? (No out of Bounds / Out of Bounds)

I've tried several times and I just clipped into the wall a little and then bounced out.I guess MDHR has fixed it or I just lack of this skill.As for No OoB/OoB,these category maybe benefit runners like me who cannot use this skill,but I don't think it's fair.Of course,if this bug was truly fixed,then it's necessary.
