Invalid pointer error at skeles

Description of the bug
:
What is supposed to happen?: Im not supposed to crash when skeles hit me ?
Where did you find and/or notice this bug?: at skeles
A step-by-step guide to re-producing this bug (optional): random crash
Extra information (optional): I have the latest files + the 1,1 leap files
// lost lot of my nx stuffs when i logged in after crashing, idk if that might be related to it ?

 

ehh... I think it might be related to nx expiring, my edit's wouldn't be the reason i got this crash ( as they are just img changes and i haven't done any other changes that that )
// only edited char and item wz fyi *and only changed raw img's*

 

Also, Autoassemble was in the same map as me, and he didn't get the crash ( he have the exactly same files as me )

 

mmm was just the nx clothes i had on me, and i still got my other nx stuffs like my pet and so on( bought them at a later date )
I don't think i lost anything else that i didn't see on the notice text when i got back online, at least nothing i can think of

was grinding with Autoassemble , and like i said in the last post he got the same files as me and he didn't crash ( i have just changed some img's in the char and item wz so no big changes, really doubt it would cause a crash like this)
but once i got back online after the crash i didn't experience the problem again, so might have been a one time thing related to the nx. or at least thats the only thing i can think of unless using a skill/buff or jumping down while getting hit by a mob might have caused it
TL;DR^
I was grinding and suddenly got a random crash
