map event trigger

It looks like it starts at $CC72DC. From the event dump:

Code:

Bit $069 is set after finishing the mine cart ride.

In FF6LE, there's an event on the tile where you enter the research facility (on map $106) that calls that event (event #21). You probably don't want to remove the event as it also seems to change the map you exit to when you leave the facility, so it's probably best just to edit the event.
