Are the 14 resource cubes of each color intended to be a limit? Some specific examples:
* If there is a line of 3 green discs, and no green cubes remain (in the supply) what happens?
* If no red cubes remain (in the supply), can a store be built?
I assume tracking opium use is always possible because you can place the cube you just spent onto your own track to mark it.
Thank you for pointing out the parts that we did not clarify in the rules.
The resource cubes are UNLIMITED. If there is no cube left in the supply region, you could use small items to replace it.
