Hi,
So in theory Decker shouldn't crash, even if you write something that doesn't work. And the things not saving sounds like an issue. In the interests of figuring this out so it can be fixed for others, can you let me know what you'd put into Dialogizer that crashed things, so I can try and see if I can recreate it? And also, what sort of things weren't saving?
Also, just want to mention this was a really lovely project that turned out really well, great work!!!
