+Something peculiar just happened. I had the MBP with me while I was out and was editing documents with no connection to any of my machines.
+
+I usually stop the assistant at home so that it only runs on one machine at a time because of https://git-annex.branchable.com/bugs/OSX__58___Pushed_changes_are_autocommited/ but because I was out, I started it.
+
+On startup, it said that it was trying to repair my repo. I shut it down because it couldn't do any repairs without a connection to my machines (and it wouldn't succeed even if it did unfortunately).
+
+I ran `git fsck` to see what happened but, to my surprise, it returned no errors besides missing reflog entries from previous corruptions. `git gc` didn't error either.
+
+I commited my changes manually while I was out.
+
+That was about two days ago. I synced my changes manually at home where an unrelated and trivial issue happened during which I ran another successful `git fsck` and, after fixing that issue, I started the webapp.  
+It was attempting to repair again and was complaining about a thread having crashed (logs below).
+
+Now however, the repo is actually broken with missing blobs, trees and links everywhere.

+
+I haven't set the fsync option yet but this system hasn't been restarted in a long time and the corruption happened while the system was on; right in front of my eyes basically.
+
+I'll now manually fix the corruption again by rsync'ing the `.git/objects/` dir to the state of a working repo's.
