Ah, okay...After a few hours of playing I finally get why there's no ores! There is a little bitty tiny problem with it though...
The reward tables are reversed for the epic and basic bags...
Let me explain for other. (Basically) The creator removed all the ore, so no mining for a stack of iron and bringing it back to base to smelt it. Instead, all the ore is replaced by silverfish eggs. The silverfish drop epic reward bags which contain the ore you would have mined if they weren't replaced with the eggs! (Again, this isn't entirely true, but it's basically how it works....) I actually like this. It's pretty novel. You gotta kill to get ore. Lol. However, all the epic bags are utter crap. Luckily though, the basic bags I get from killing my sheep farm give me all the ores I need, so screw killing all those silverfish...Sheep farm for diamonds. Makes it too easy and breaks the combat focus that the pack is intended to have...
Just thought I'd leave this here and wait to play again until it's fixed. I'll be looking forward the next update!
