From hyperium_872 on the curseforge page:
"Having problems with wallrunning. It'll stick me to the wall, but any inputs will drop me. Am I doing something wrong, or is this a bug?"
"found the issue, it was conflicting another mod called "wall-jump!", have now removed it and can now wall run."

Not simply a conflict with just wall jump.
Elenai Dodge 2's ability to dodge in midair.
And Move plus's ability to grab ledges.

All fail when under the influence of some form of physics based grapple hook system. Whether thats yeeting yourself with forcefield or ender rod, or trying to clear a gap with a swing from a grapple hook and grabbing the wall/ledge with wall jump or move plus.

This also has the effect of what I can only guess is making wall run/jump from this mod's enchantment also break.
