End of the game scoring
1. Gold - "First, convert treasure chests and one-time (1x) progress tokens that grant gold into gold on their owners' gold tracks."
Well, what I'm concerned about is the missing phrase "which haven't been converted yet". If I converted a chest and/or a progress token into gold earlier in the game, I don't do it again during the scoring, right?
v. con·vert·ed, con·vert·ing, con·verts
1. To change (something) into another form, substance, state, or product; transform: convert water into ice.
If a chest has been converted to gold, then it is no longer a chest but 3 gold. The rules are quite clear. You cannot logically deduce that the process can happen a second time.
