This is a forked version of the original mod (https://mods.factorio.com/mod/ore-unlimited) by No0Vad: https://mods.factorio.com/user/No0Vad
updated to fix ores from the "bobsplates" mod not being changed to unlimited correctly.

Adds the Ore Unlimited item which allows you to change the ore fields to unlimited, or back to normal with fixed amounts by holding SHIFT instead.
If you want really high amounts, use a high number for the yield in the mod settings.

IMPORTANT!
Be sure to restore the ore fields to normal first if you want to remove this mod!
