Cannot click on Clamshell to receive pearl and cannot exit map afterward

Description of the bug: (optional screenshot/video):
What is supposed to happen?: I climbed all the way to the top, and clicked on the shell but nothing happened. I tried to use @gm command, nothing happened. and I tried to exit map, nothing happened.
Where did you find and/or notice this bug?: in the Roel Big Pearl Jump Quest

 

I think I did.

Should I repatch?

 

Ok, i will try and see if it works.

 

Ok, so here is my test.

I was using this Cosmetic WZ skill edit from Poofcakes https://forum.maplelegends.com/index.php?threads/poofs-cosmetic-wz-edits-2-0.17801/
So i tested to see if the edit was the problem. However, it wasnt.

I patched my game the 9th July once and extracted the edit. The result was it still stuck after I clicked onto the npc to move out and canceled that option. The same happened after I repatched and didnt use the edit. So I used the @dispose command and it worked.

The problem only appeared after clicking on the npc to move out, however canceled it. @dispose fixes it, but isnt permanent. If you repeat the step, you need to dispose again.

Basically you can only click onto one npc in that map ONCE.
