There are 2 issues with ledge grabbing in the beta, both able to be observed on the 2 different versions of Le-Koro.
The first one, affecting Main;
If you ledge grab on certain ledges (such as that walkway in Le-Koro or the FVIL token door), there's a slight chance that you will keep falling through the animation. In that case, you will instantly teleport to the bottom of the ledge (no matter how far that is) once the animation finishes. This completely prevents you from ledge grabbing that walkway in Le-Koro.
The second one, affecting Rebuilt:
Here, you can successfully ledge grab that walkway in Le-Koro, however you'll get stuck. There are only two ways to get out of that, by dying or using the debug camera.
