Goals from Obileye and Forrest at the start of both halfs for Livingston put them level on points with Aberdeen, despite a Montano sending off towards the end.
Stephen Glass reaction
"There is no surprise, we are not surprised at what the game became, that's the disappointing thing.
"We've handled that a couple of times already, once here and once at home this season.
"There is no reason for us not to handle that other than mentality and thinking we are slightly better than we are, and not handling the ugly side of the game.
"Once we started doing that late in the game we looked like a team. We didn't look like a team early on."
