I'm 358.2% sure Ashley will close this as non-suitable, since he cannot debug a whole game for you - you need to find the element that makes it crash, make it repeatable and then add it into a small capx.

But in this case I don't even think it's a bug - I could touch the star no problem and kept on moving.

Also, what do you mean - Construct crashes? - does it show an error message (if so, what is it?), does it just hang, does it just close?

I don't know what causes Construct to crash or why the variables aren't working. I've tried reordering the events, but it still doesn't work. When Construct crashes, I get an error message that keeps popping up every second until the program closes.

What is the error? Can you copy the error message here or take a screenshot of it?

I don't know how, but now I've realized I've lost a lot of work because Construct isn't saving anymore! I hit Save, close the program, reopen it, and nothing is saved.

I haven't experienced any crashes today. Events still not working, but working on that.

Closing, please follow the bug report guidelines, and please stick to one bug per report.

Crash: can't reproduce. Please check your graphics drivers are up to date.

.capx: You have over 150 events. To prove the issue is a bug in Construct 2, and not the very common case where people submit their own mistaken events as bugs, please provide a minimal .capx as per the guidelines.
