There is a really annoying bug in where you hear pop sfx noises on the background when i don't even have an SFX running. It's really annoying and i feel like i want to pull my hair because there isn't nothing i can do about it.
EDIT: It only happens when i'm switching screens. The problem started ever since i imported my script file.
See these lines?
temp=get_arg(sarg1,i,ri)/10000;
sfx(temp);
jukebox(temp+(ZC_MIDI_COUNT-1));
I commented them out then ran your quest file which shows that the strange goings on is your own doing. I suggest you double check your script file, or do a search in those related files if you like for "Game->".
Confirmed. Not a bug. It was an annoying code in my Global Script file. Thanks!
