Words with Friends: played blank tile as blank, glitch?

I somehow managed to play a blank tile as a blank (6th row, 13th col):

and got the double word score for TACT.

Is this a glitch, or a legitimate move? The HTML for this tile (note that zynga numbers rows starting with 0):

<div><span></span> 

(It's game number 3950502083 if anyone from zynga's reading this)

Thoughts?

Doesn't appear to be a bug. If you search for "tact" in the Words With Friends Dictionary, (direct), you'll see that the word "tacts" is also an entry. Although I can't imagine the word tact having a plural for any reason, the blank tile was probably recognized as an S, not as empty space.
