When I try to open some routes in Pokemon Emerald for editing in Advance Map 1.95, I get the error message "ERROR: (ENotAPointer) AdvanceMapError(5): Value $DF1E0A". The value is different for each route that has this error. When I click past it, the Pokemon Encounter lists have been erased (which were what I've been editing with Advance Map).
I would imagine that this is because it's trying to reach a hex value that either doesn't exist, or is filled with stuff that can't be read properly, or something like that, but I'm relatively new to this, so I don't actually know. The only thing I've done is change the Pokemon Encounter charts, so as far as I know, I haven't done anything with scripting. Can anyone tell me what is going wrong?
