I was trying to put the bot to mine multiple blocks with exact amounts and the go to my home waypoint
the command is this:
.b mine 128 iron_ore, 128 coal_ore, 64 diamond_ore, 128 redstone_ore; goto Home; path (Home is the name of the waypoint).
wheres the error?

1. #mine only takes a single count argument for all ores (#mine 128 iron_ore coal_ore diamond_ore redstone_ore) and compare the sum of the ore counts to that value.
2. Baritone doesn't have a feature to chain commands so unless that's an Impact feature the ";" doesn't work (assuming you are using Impact because of the ".b").

There was an attempt at per-block counts in #2088 and one at returning home after mining in #1064 so you can have either feature on an outdated version of Baritone by building them yourself. Not sure whether they can easily be merged together because they both heavily modify MineProcess.
