Steps to reproduce:
- Create new document
- Add text to document
- Close document
- Open new document
- Add different text to document
- Do Find/Replace on document with multiple matches
- Step through replacing each instance of the text
- Upon replacing the last piece of text, Sublime Text 2 will insert old text from the previously closed document into the current document.
Let me know if this issue is unable to be reproduced and I will review my steps more carefully.
Awesome editor by the way, very impressed and will purchase when it comes out of beta!
