But just last week I learned for the first time that cancelling a building while it's building or researching refunds the cost of that unit or upgrade. All these years I've manually cancelled things before they die... and sometimes necessarily so because the building survives. This is thanks to the new feature of displaying refunds for canceled baneling morphs etc, and realizing the refund was happening even when killed. Went into a vs AI game to test buildings, and mind = blown.
If that change was never made I might have never realized.
Another thing is I only recently realized banelings didn't count as light units, when it was mentioned in a cast I believe at MLG Dallas 2013.
I suspect there might be more. Anyone else have these moments?
