Synthale keeps dissapearing

wurmix

Hi,
i noticed that my supply of synthale keeps get thinner without any notice.
The next time i needed some some synthale for duty officer assignments,
I bought exactly 10 bottles, but used only 6 of them.
The sittuation repeated itself, because a day later there were only 3 bottles
left instead of 4.
Is that normal ?

Do you have any Tribble slotted in the same space where you keep your synthale?
