Glitch workers can do a few jobs (please reply with others that you can think of); farming, mining and guarding. Any drops that they come across that are specific to their jobs, they will pick them up and drop them off in a storage container aligned to their job. Farming Glitches take farming related drops to Farming Containers. Mining Glitches take unprocessed ore to a furnace close to a mining container, or if a furnace can't be found, they will take the unprocessed ore to the mining container. Each container has 128 slots.
