Discover v4.88: Mining - Bugs, Balancing, and Feedback

[Echo 7-7]

It's the thread you've all been waiting for! Hold nothing back* as you post to your heart's content concerning any and all aspects of mining.

A few rules:

1) Tag your posts appropriately with a clear title.
Your post will either be about ore mining or basic mining.
Bug: you know or suspect you have encountered something that is not working as intended.
Balancing: you would like to suggest an adjustment to existing values such as drop rate or field position.
Feedback: you have something to say regarding the overall mining system that doesn't come under the other two categories.

2) Don't post in reply to someone else's post. This is not (currently) a discussion thread so clear reporting of (potential) issues is the priority.
