Bug fixes.
Since downloading this version it crashes whenever I try to save, giving me the "Aw snap!" message about being out of memory (doesn't happen with previous stable version or any other tabs)
"Aw snap" means the browser crashed, not Construct, so it may actually be a problem with the browser. However in general if you run in to any problems please file an issue here following all the guidelines: github.com/Scirra/Construct-3-bugs
I have had no luck after a few days of trying a lot of possible solutions, so have submitted a bug report :)
