Entities, and property regions both crash the editor... but it appears the application log states "notImplemented exception"... so i'm guessing those don't function quite yet

Some tiles appear like this in the editor, despite loading properly in-game. Minecart rails do the same thing.

The OpenAL32.dll you have packaged in the Editors folder for the map editor was only 119kb, yet the same dll in the main installation folder is 2,150kb.... this got me curious, so I replaced the smaller sized dll.

Program ran, imported a legacy map, started placing some tiles... but it's late, so i'll play with it more tomorrow

Two application error logs created on each launch attempt...
Faulting application path: D:\Faldon\Editors\FaldonWorldEditor.exe
Faulting module path: C:\WINDOWS\System32\KERNELBASE.dll
