Same thing happened to me when scaling a map in 1.6.4. Just like Poker Chen steps: Made map (#0), scaled it to x8 (became #1,#2,#3) and explored a bit. made map elsewhere (#4), scaled it (briefly #1, then #5), again (briefly #2, then #6) and to x8 (briefly #3, then #7). Checked map #3 with each scale step, it was fine until it blanked the explored part when enlarging map #6 to x8. It must be the brief overlap that does it. Made map (#8), scaled it (briefly #5, then #9), again (briefly #6, then #10) and to x8 (briefly #7, then #11), found map #7 blanked. The copies of my maps on the wall also went blank.
When I restarted Minecraft, all 3 maps were back to normal.
It would be nice if the number stayed the same when scaling maps. It's better to have maps #0,#1,#2... instead of #3,#7,#11...
