I have reproduced the bug, and I believe the error you're experiencing may have to deal with the print message action. I'll publish a patch tomorrow. The project file is off by 2 values and won't load without a manual fix if this is indeed the issue. I do apologize for the set back; I don't have testers to find all the issues and I do appreciate your support.

Honestly, thank you so much for working on producing a patch so quickly. My original worry was that I had made the project too big somehow, and I had hit a wall. I actually never closed the application, I copied the project to work on it from a different computer and that was where I ran into the issue. Hopefully if I remove the Print Message from the game and save it, I'll have a working save that still has all my stuff without crashing.
Glad I'm able to help catch some issues, and thank you so much for responding so quickly.
(edit: my attempt actually did NOT work... >_>I'm now very hesitant to close the project even though I know I have to lmao)

I got the crash again after re-adding the lost stuff without the print command. I opened and closed it a few times to test, and it broke again after i added two triggers. One was when you put an item in your inventory it removes two commands, and adds two, one of them being the same because I was trying to make sure the commands were always in the same order. The second trigger was to add the command that originally had the print action in the original version.
That information was very helpful, thank you very much. I reproduced the bug and found the issue deals with the SET CURRENT ROOM action. The editor wants to read 3 lines from the project file, but the action is only 2 lines. In the case of this problem, the project file is fine, and the editor needs a patch.
