Tilemap patch brushes; Flowcharts, templates & scripting updates; Lots of bug fixes.
Well, I guess this is what beta releases are for... sigh. The "Invalid indexes" will be working as expected in the next release.
No problem! Happy to test it out. Again it would also be nice to allow 1x1 patch brushes, or simply add that same "invalid indexes" dropdown/checkbox to the brush in the editor so the editor can use the same functionality. Thanks!
I just remembered I did include the option for empty tiles to be ignored in the editor. You have to press ALT when drawing.
