I have had to get someone to make me a char with hiding skill to clarify what you said; which is true. I have already made a solution to fix but i'm in the middle of testing it - i notice some bugs(can't mount while using it etc) but you can see who's invisible once again
Milson22, have you read the guides? if you're using xtrap bypass v1 to cheat then that's the incorrect way of using it.
Xtrap bypass v1 is for development/test hack purposes only(not for playing)
YCS hacks does not need any bypass to be able to use it but only YCD;
Xtrap bypass v2 is for YCD and other 3rd party utility such as BEM/Uopilot etc - you can even see the guide/tutorial i've made on the first thread to show you that BEM can still be used even today(after xtrap updated to 59XX)
yadrod, as mention on the first line of the thread: It requires a key to be able to use it.
