Sometimes it hits the cache when the files are not on disk

Hi

This tool is nice and convenient, thanks. But recently I started getting a very strange Shroedingbug.
Quite often if I clear the previously generated sprites and then run the build, it would report that the files were not changed, and skip writing them to disk. This ultimately leads to the build failure.
I wasn't able to reproduce it in debug mode, so it can be some kind of the race condition.

For now, I have commented these lines in my locally patched copy of the plugin:
