Re: bridge movement:
Second the suggestion. Basically what you're saying, 300win, is that your mandolin went sharp the equivalent of a one-sixteenth movement of the bridge. What normally makes a mandolin go sharp is expansion of its wood; the instrument is "bigger," which tightens up the strings. I keep my collection in a fairly humid environment, my basement, and I find that an instrument tuned to pitch and played "upstairs," then left in the basement a few days, will be sharp when I bring it out again.

I have often recommended the Taylor Guitars Tech Sheets for their discussions of humidity's effects on stringed instruments. Although they're aimed at guitarists, there's info there that can be helpful to mandolin owners.
Secondly, I applaud your decision to be less combative in your postings. We're all trying just to get along, here, and exchange information and opinions with other mandolin-playing friends.
