I found that the Mineshaft only puts out 1 iron ore at a time, and considering the time to mine, and the risk of Too Deep:Infestations, I decided to adjust this. As 1 iron one was also driving me crazy (Why only 1!?) I made a change to the files.

Here's where and how to edit it yourselves if you find "1" iron ore, too small an amount. I set it to 20 myself, as I felt that was more fair-

*Step One: Go to C:\Program Files (x86)\Steam\steamapps\workshop\content\294100\2553700067\1.3\Defs\RecipeDefs
(Please note, your folder might be different numbers for the file, good luck finding it, and this is for STEAM)
*Step Two: Open Recipes_MineShaft with Notepad (or something similar, so you can edit the XML file). I suggest saving a backup in case you mess this up somehow.
*Step Three: Use Find and enter "Iron" to locate these lines-
<jobString>Mining 1 iron ore.</jobString>
<products>
<DankPyon_IronOre>1</DankPyon_IronOre>

Change the "1" to a "20", this changes the job to produce 20 iron ore, and changes the description to mining 20 iron ore.

Remember to back up the file before you did this, and then save when you're finished. You can also find Silver and Gold in here, but I didn't adjust those. Have fun.

***To the Medieval Overhaul mod dev, I LOVE this mod.***

NOTE: If you find this broke something, or messed anything up, please replace your file with the backup you should have made. This was a quick fix on my end and I didn't bug test it at all. Good Luck.
