Right now the limit of drills is 10. Before i don't think there was a drill limit which was much better because you could get multiple ores at a time with 5+ drills each. There are 7 different ores and with a drill limit of 10 you can have 1 on each and 3 leftover that you can put wherever you want. This makes it very hard to get enough materials so that the machines wont stop for 5 minutes every 30 seconds. Increase the drill limit to 20 or 30 or just make it infinite cause its very annoying having to wait alot of time just to be able to get 1 crate or armor or whatever you want to craft.
