This is the problem. I can patch that... but there are other exploits. Then I can patch those, but there are more...

When I say 2-player mounts are nothing but glitch-fests, I mean it. Their implementation is poor and all it does is introduce ways for people to get on walls. Almost any sort of wall-glitching can be traced back to them. Now we're left with the mess and can do nothing but sit and tediously clean up each individual exploit players seem to find with them since getting to the root of the problem is nearly impossible now.
