I've taken note of this problem, i'm not sure it can be solved without removing the part of script that prevent FPV glitch. I had to decide between FPV glitch or the exploit. I personally think FPV glitch is a bigger problem so I decided to keep the script. Even though, the exploit is still disallowed if done intentionally and it's punishable.
I'll do changes when i find a way to prevent both & you are free to post suggestion if you have better idea.
