Hi @tinny77, any idea how to reproduce this issue?

littlebee commented 7 years ago

I'll work on a PR tomorrow to add guards to prevent this and this issue: https://github.com/littlebee/git-time-machine/issues/104. I think both are happening when the editor has gone away and _resumeUpdateDiff() resumes.... that's all I've got right now.

I've been able to repo it on the Mac by clicking and dragging in the git-time-machine time plot. The suck part is that once it happens once, it will continue to happen when ever you save the file until you reload atom.
