Only the red disease to go, and there's only one red cube on the board, in the same city the Medic is standing. Another character researched the red cure.
The Medic automatically removes the cubes of cured diseases in the city he/she is in, even out of turn. According to that, he would remove the last red cube at the same time the cure is researched and the disease has been erradicated.
But the rules also state that the game ends as soon as the objectives are met.
My understanding is that since both things happen automatically, the two of them actually happen. But some people in my group think they the game ends before the last red cube is removed. We are unable to agree and we would welcome some clarification (or at least more opinions) on this
These are, word by word, the "conflicted" rules:
Rulebook page 6:
If a disease has been cured, he automatically removes all cubes of that color from a city, simply by entering it or being there. This does not take an action.
The Medic's automatic removal of cubes also happens during other players' turns.
Automatically remove cubes of cured diseases from the city you are in.
Rulebook page 14:
You win as soon as you meet the necessary number of objectives. The game ends immediately, even if it is the middle of a player's turn or a series of outbreaks.
