Problem description: runtime error: Cannot modify null.loc.
proc name: LoadSave (/ACiD_Handling/proc/LoadSave)

If anyone could help, i'd appreciate it.
F["Loc"] >> M.loc

You can't save and load locations like that. You have to use seperate variables for x,y, and z. Your location is a turf, and everytime the world is opened or close, entirely new turfs are created.

I must speak with you about a library or demo of yours.

You can save and load locations like that, I admit, I was being lazy with it by not saving seperate x,y, and z in the savefile, but, the problem was fixed by taking out mob/Logout() and replacing it with


client/Del()Handle.Save(mob)






EDIT: Yes, and I know the snippet is horribly chopped, I was rushing to get it to him, and as we speak I am going through it and optimizing it, and fixing some useless things.
