Distilled Water No!!!!!!!!!!!!!!!!!!

Quick question guys. Ive been using a cigar oasis for years now but the other night i filled it up with about 10 - 15 ml or so of TAP water!!! This was by mistake as i have one bottle marked distilled and the other tap and i picked up the tap water by mistake.

I know over time tap water can clog your hygrometer and taint your stogies opening up the possibility of mold, i have never had mold before and store at 65% Rh and 67F. Will this ruin my stogs? I have topped it up with distilled water today but has the damage been done
