2 min minor out for the rest of the game

So this has happened twice now. 

I get called for a 2 min minor for interference with 28 seconds left in the first period.

I go to the penalty box and the period ends. The second period starts and I sim the rest of the penalty only to find out the second period is now over.

Hhhhmmm that was weird.  So the third period starts and I am still in the penalty box.  I sim the penalty again and now the game is over.

I just figured it was a glitch in the game. Then just now. It happened again. This time after sitting in the penalty box for the entire second period at the start of the third I decided to wait.

at the seventeen minute mark I decided to sim the penalty again and you guessed it.  The game is over. 

One time is a glitch. Two times it's a bug.
