Hi all, thanks for making this thread. I've been asked by the TERA team to have folks experiencing this submit a ticket to Customer Support giving as much detail as possible. Screenshots and video would be an incredible help, demonstrating what actions result in being stuck unable to jump. Please include whether you are using default keybindings as well, and whether or not you've attempted to rebind jump to another key after the glitch happens. It will help narrow down whether this is some kind of input issue or something going on with skill mechanics.
