Hello Thank You for using this plugin! Have you tried calling the following function?
Ritter.MapTransform._compatabilityCheck();
(spelling lol)
This is a compatibility check function which gets called every time tile data changes within my plugin.
If you call it manually after changing the tile data elsewhere it might work.
As far as the boundary system plugin I've been considering adding more shapes for boundaries as well.
Currently there are only rectangular boundaries available though.
I don't know about compatibility with Altimit at the moment, I would think there's a good chance it does work with it though.
Just be sure to spawn the event on a tile.
