Hi! I'm not sure if this is helpful, but I've found that a lot of complaints about glitching on head parkour jumps, so I figured I'd post this!
If you don't know what this kind of glitch is, (lucky you), the playerhead jump glitch is a glitch that causes you to become stuck infinitely jumping on playerhead blocks. To fix this, simply shift to the edge of the head, and you'll snap out of the glitch! For some reason, it doesn't register that you're standing on the head, and it lets you walk normally. This makes jumps sufficiently harder, but it does fix the problem!
If this seems like too much effort for you, then I'd just say move to a better version. This is just for those who are too stubborn to change versions (like me).
