Hi,
There's a severe data loss bug in recent releases, including 2.0.16, where trying to undo an edit operation in the editor results instead in an undo of an operation in the file browser pane. If the sound is not muted, you may hear the sound of a file/folder being moved to the trash. But instead the file/folder just vanishes, loosing the work in those files/folders. When this bug occurs, restarting TextMate offers a temporary workaround. Until it happens again. I'm using macOS 11.2 if that's relevant. I'm a registered user of TextMate since version 1.x. Never until the latest releases I have come across this bug.
Cheers, Paulo
