Project drawer allows duplicate files to be created
1) Open the project drawer
2) Right-click a directory in the project
3) Choose New File
4) Type the name of a file that already exists in that directory and click Create
TextMate will add a file of the same name to the directory list, causing confusion. It seems the only way to get rid of the duplicate is to close and re-open the project.
