PROTEIN. WATER. LIQUOR.
Suppose that only left one space in the caravan board. What happens if the supervisor lands in one of the spaces where two cubes can be sent to the caravan and tha owners of the cubes decide to use camels to send cubes from their supplies?
Tha active player decides what cube goes first. Then the caravan is scored and the cube from the second player is send to the first place of the caravan?
The above answers are correct.
Just to make sure you (or I) aren't doing anything wrong. It shouldn't matter if camels were used or not. Cubes would go to the caravan either way.
