The bot will cut roots and burn them for the first time, then after it burns a full inventory of roots, it will chop again. But will not burn the 2nd inventory of roots. That is the only problem I'm having with the bot.
Exia Miner is great but the only problem i have is in the dwarves mines, it doesn't deposit the ores in the dung area. It'll just sit there, but once I click on the deposit box, it will continue as normal.
