I first noted a strange thing when using inkscape SVG files as level data for a game. When updating both graphics and SVG file I noticed that the graphics was updated but not the SVG file.
I had to uninstall my game and then install again to get correct behaviour.

Then today when removing a wav-file and still had code trying to play it, I got a warning in Windows simulator about a missing wav-file.
Then upgrading the game on my Galaxy Tab 10.1 with new code, the sound was still playing and had not been deleted on apk upgrade.

I have never experienced this on Android SDK so I was really surprised about this.

Am I missing something or is this a bug in the build process?

I'm using Corona 2011.648.

This is a high priority bug and we plan on fixing it within the next couple of weeks.
