The old LE had the WoB/WoR pointers hard coded.
Changing the
order of map data and tiles instead of using the one originally slated by Square was one problem. I've fixed this in a test build of ME. Using ME first, then LE was fine, but corruption problems would come again, when returning to ME then to LE.
The second problem was that ME reprogrammed the map/tiles pointers, when space was available. Say you made the WoB simpler, the compressed map would get smaller. Then, saving the WoB tiles would be "earlier" than 0x2F134F. FF6LE didn't like this.
So yeah, I don't really like to remove features, so I had to get this FF6LE to work like FF3Ed did for the overworld maps

PS: the FF3usME "ROM manager" will lie to you when using the new FF6LE: it'll say that the expanded data (if in use) will be in bank $F0. This is not true!! Bank $F1 (or whatever you changed that registry key for) will be the real expanded bank. This is just a display bug.
PS2: on a similar topic, when using expanded maps or dialogs, do not save twice. Save once, close FF3usME, then reopen. This is a nasty bug that Gi Nattak recently found. There is a counter in the save function that should get reset but doesn't ATM
