Yeesh, that's no fun.
Half the time it seems people have their own internal political reasons for doing weird stuff too. Nothing like being the victim of someone else's office politics. Well I hope they pay you well at least.
If it makes you feel any better, I just got informed I was given the wrong formula for a calculation I did a while back. I don't have the numbers I need to rework things, so I have to back-calculate those from numbers I do have, and then redo the relevant number-crunching on 90-some different spreadsheets. Then take those numbers and redo histograms that might be part of the supplemental materials if this next paper ever gets off the ground. 1pm is good beer time ya?
