[Map✓] Map error in game

[PKMNTrainerGui]

I edited the Viridian map, and when I'm walking on a map spot, the game resets. How can I solve this ??

I assume you have edited, or delete the oldman sprite?
Backup your ROM and delete ONLY the script that has the oldman overworld number using Advance Map then see if you can enter the city.

It worked. Thanks Zhang!
