Ravine should generate before an abandoned mineshaft.

Love ravines, love abandoned mineshafts, love when they intersect (best yet with a stronghold, too).

However, by the way the ravines cut through the mines' structures it shows in which order they were generated. Just for realim's sake, wouldn't the geological event have occurred first? When there is a mineshaft on both sides (same y etc) with planking for a floor, it would seem appropriate that they would be connected. Lava falls would still be able destroy some 'bridges', the same as internally.

Oh, and please consider this a vote for a cave update, sometime soon? :) Thank you for all the amazing work.
