After clicking "Save" AWB will, from time to time, drop all edits and restart on the same article from scratch. This would be fine if the only edits were automatic ones. In each case I remember, I had spent considerable time hand editing the page. However, it could easily have also occurred when only automatic edits were made as those don't have the same level of frustration associated with loosing the edits and are not remembered as well. In these cases autosave.txt does not contain the text from the previous edit, or is overwritten with the new text. Simple fix: do not clear/overwrite autosave.txt until a hand edit is made in the edit box for the next article. This would permit the user to go find the last version of the text in the autosave.txt file for the previous article if there was a problem prior to starting hand editing work on the next/same article.
This happens often enough such that I am considering developing the habit of copying all the text to the clipboard prior to saving.
It would be very helpful if there was a way to auto-recover the prior edited text. Off the top of my head ways to do this would be to ping-pong between two autosave files; have a few that are used in rotation; have one associated with article name and edit start time with only X kept; etc. Where it switches between them upon the user indicating save. However, this much larger solution would be an RFE.
OS: Windows XP
Workaround: None; copy text elsewhere prior to save in case of failure.
