Overworld map all ocean, can't move

Sorry if this is in the wrong place or if I've missed some obvious information; I'm just getting into this.

Using FF6LE, I changed the WoB overworld map which included shifting Narshe's position. I changed the exit in every Narshe map I found to reflect the new X,Y of where Narshe is, but whenever I exit with Locke and Terra I just end up in the middle of the Ocean. Additionally, the minimap did not change, but I don't know if that is based on the actual map (I assume its not).

Any help/advice/links would be appreciated.
