My latest quest is do 2 searches for coal.
I have 6 industrial coal mines and no free spaces to find coal deposits. I don't want to deliberately collapse an industrial mine so I have no interest in doing this quest. However looks like I'm either:
a) stuck with it, with no further quests
or
b) run down a mine I don't want to run down.
Not good. Please add a cancel option to these quests.
