Quick question before isolating a co2 leak.

Came home last night to find the tank empty. I hit the pressure relief valve on my lid and the keg was not pressurized.

Here's my question. If the tank runs out while the gas disconnect is connected to the stem, will it purge the keg of co2? This all happened way to suddenly and I'm thinking I may have inadvertently opened the ball valve on an open regulator the night before. (dual regulator setup) I had checked for leaks with starsan in a spray bottle when I hooked it up 2 weeks ago and everything seemed fine.

Short answer, yes. It's why I always close my line valves and tank valve between uses.
