Board Game Arena

I have noticed that in all games at the very last turn, if you use a dice to increase workers, that extra workers (+2 or +4) don't get counted in the total points at the end. Is this a rule of the game or a bug? Has anyone else been experiencing it?

Do you have a particular example where this does not happen?
In your most recent game https://boardgamearena.com/table?table=378993003 you end up with 4 workers left and the log states you receive the correct 2 points (it's a point for every two remaining workers).
