Seems like the main plugin "Cyclone Map Editor" not work properly with 'Altimit pixel movement'.
The location of the 'mouse' not work properly (no console error) with 'altimit pixel movement, probably because the line code lines below (in the altimit pixel move plugin), can you try to look it up and see if you can fix it without the need to disable the code lines?
Code line 01:
var DOM_PARSER = new DOMParser();
var PARAMETERS = PluginManager.parameters( 'AltimitMovement' );
Code line 02:
prune.forEachProperty = forEachProperty;
Side question: did you find time to fix the error with this plugin (you said something about making it leading the all map to fix it), at the moment I still can't use it.
