I finally got around to upgrading Unity to 2019 LTS and ORK to 2.30.2. And, as expected, have run into some issues that I can't figure out.
EDIT: These still function when using the ACCEPT key (enter by default) - checking my settings Events set to be interactive, chests (box type), and shops have all stopped working. They no longer activate when the item is clicked. I did create a object and added an new event to see if I just needed to rebuild everything; it didn't work either.
Events set as a trigger still work fine.
EDIT: ORK Editor issue appears to have been solved with the deletion of ORK and re-import. Saved my project and copied it back over after the re-import. The ORK Editor just shows tabs across the top and nothing else with the following errors displayed in the console ArgumentException: Getting control 1's position in a group with only 1 controls when doing repaint Aborting NullReferenceException: Object reference not set to an instance of an object
As a test, I created a simple script to make sure "clicking" an object - at least, the way I always did it -still works. Yep, still works just fine.
I'm going to delete the ORK folder and re-import to see if that corrects the editor issue. Question: A 47MB project file - is that getting too big and may be causing me issues with the editor???
