@lucid First off, I want to mention how amazing Spriter is. I'm currently designing enemies for my game, thinking about their attacks and patterns and everything. Spriter opens up so much possibilities in combination with Construct 2 that there is pretty much no limit. Really inspiring!
But I encountered an error. Couldn't really find someone else mentioning this, my apologies if I skimmed over it in my tired state but maybe there is a quick answer for this.
I just did a try-out of a character in Spriter release b8, and it froze and shut down, this is what I did;
I started a new Spriter document and imported the bodyparts of my character which where all prepared in Photoshop (rotated for better scaling in Spriter). But when I dragged the head and seperate hair object in the project I remembered that I didn't adjust the pivot points so I deleted the two objects by selecting them one at a time and pressing the delete key. After I'd set all the pivot points for all the objects I wanted to delete the "empty" head and hair duplicates once I noticed them in the object window which displayed all the current objects in the frame.
It was not possible to delete them from the "current objects in frame" window by pressing the delete key and I tried right clicking but that didn't do anything. So I accidentally pressed the red delete key in the animations window from which I knew wouldn't make a difference because that handles the animations, but I tried it anyway. After that I pressed ctrl-z to undo. Then the program froze and stopped, trying to find a solution like Windows (never?) does.
This is all I know for now, hopefully this all was clear enough. If not I'm happy to answer all your questions and help you out!
