I suspect you used a microtiter plate with a loose fitting plastic cover
aka a tissue culture type plate, and the outer wells dessicated while the
inner ones didn't. I have had best luck shaking the plates quite fast
(„250RPM) with a rich media like TB. Too bad "Mr. Microplate" or whoever
doesn't make a baffled bottom 96 well plate.

PS the 48 prong template sold in SIgma is great for going from the 96 well
plate to solid media.
Good Luck!
