Flooring Tile - Didn't moisten the hardibacker before tiling (doh?)

I am almost done rehabbing my bathroom and I'm halfway done with the floor tile. I remembered reading that I should first moisten the hardibacker board first prior to tiling. The remembering part just took place which puts me about 12 hours into the curing process.

Is the thinset cure going to be premature? Am I headed for a big problem?
I've read that the hardibacker (or any backer) will suck the moisture out of the thinset causing a poor cure.

The bathroom floor covers about 35 sq foot less a 42" vanity and toilet. I'm using 12" ceramic tiles with modified thinset on 1/4 hardibacker. The backerboard is sitting on unmodified thinset on 3/4 ply.

Thanks

It is certainly a good thing to do but I think you will be alright. If the boards were heated by direct sunlight for awhile then the chances of a problem have increased but if you are experiencing winter weather now you probably lucked out.
