Err maybe I'm wrong; does anyone know if 2.2.2 is out to the public? I just write the code.... sorry about that.
Damn... is this an older (2.1) project? Or is this a project you saved with the update that has now started to give you crap?
Edit:
My superiors have informed that 2.2.2 is not out, so my mistake. It's unfortunate, since I do think that update will solve your issue, and this has been going on long enough. Hopefully that will be available to the public soon, but I'm probably not meant to comment on stuff like that.
