The last part of AuctionBotSeller::LoadItemsQuantity (in src/game/AuctionHouseBot/AuctionHouseBot.cpp) calculates a divisor inside a loop by summing all the item amount config values. For me, the values CONFIG_UINT32_AHBOT_CLASS_GEM_AMOUNT and CONFIG_UINT32_AHBOT_CLASS_GENERIC_AMOUNT are not present and therefore uninitialised and have large garbage values. This makes the divisor VERY LARGE and results in zero items being added per class. I patched mine locally by removing them from the sum; and also added a check to print out an error if the item amount becomes zero as a result of the divisor (to help find item classes that would never be generated even with valid config values).
