Maze Island overworld cannot edit/save

[Vortaka]

Hi, love the software!
There's one part of the world (maze) I cannot edit.
After simple change: I change the entry property of one of the events (let's say #37), change entry to 0 (from 256) as soon as I press Commit to Rom.
"Can't save maze_island overworld because it is 1702 bytes.
Overworld maps must be smaller then 896 bytes.
Dismiss"

Thanks for the software!

P.S. death_mountain overworld gives about the same error...

Could you try this work-around:

At the bottom of the DM and MZ maps there is a huge block of spiders. Replace them with any other tile (e.g. mountain or water) and save the map.
