So i made a mew event in frlg and put a flag to make it leave after defeat and i go there and it's just gone? when i remove the flag it's there but stays after defeat. Pls help me
I use advance map and pksv.

Sounds like the flag you're using is already set. Make sure you're not using it in any other scripts and that the game isn't already using the flag for something. You can find a list of flags here. Also I would recommend switching to XSE because most scripting information is for that tool.
