That ramp circled in the above picture is glitchy.
As shown by the Red Arrow, the lizard jumps onto a part of the edge of the ramp.
The problem is that the lizard will often(but not always) go though what should be solid ground.
One would think that they could just jump up through the ramp from the bottom.
As shown by the violet arrow,however, the ramp happens to be solid from the bottom, but not from the top.
Additionally, I was disconnected from the server while trying to maneuver onto the ledge.
The combination of all above mentioned aspects of the ramp pose as a major nuisance to me, the player.
Thanks you.
EDIT: I was using the arrow keys. Using the mouse proved to make the problem seem nonexistent.
