Hello, FYI there's a typo on p96 on the Maps table. The number "3" features twice. I assume Treasure Map should be present on a roll of 4 - 9.
Also I don't know whether it's an intentional change or not, but in OD&D III p7, it says gold will be in the treasure 50% of the time. But I can't see that mentioned on p127 of FMC.
