In areas that have a lot of surface-level differences, it is possible to fall through the floor, or begin to glitch through the floor while using the forward roll button. (Default spacebar.)

This has been easily reproducible for me inside of the Desert Temple area. Especially in the sub-area where there is a chest to obtain on a platform that requires you to activate 2-3 switches.

When you begin to glitch through the floor, you no longer walk properly or adhere to the proper navigation mesh for the map. You instead seem to always attempt to run down and to the right 90% of the time. You can sometimes get the game to begin moving properly, but attempts to move afterward will continue to glitch. While this happens, you are no longer able to target mobs properly, you cannot click on consumables on the ground or pick items up. Doors also stop functioning properly.
