Sometimes creating new sprite destroys old one. It becomes invisible and unselectible but appears exists in project explorer. Newly created sprite moves rigidly like with grid snap (it's off).
I use 0.99.97 version. I had this problem in several projects.
This is one of them(on adding new sprite dialog_text dissapears). http://dl.dropbox.com/u/6325775/wewe1.cap
Please help. Project is burning, it have a lot of events and it will be painy to do it from scratch(((
