Hi.
I just got this Error:

https://prnt.sc/26x8t6y

If you need the Save or Modpack, just ask me. I will provide both of them.

I had the same error here.

Error while running event WellPlanner::on_player_selected_area(ID 50)
WellPlanner/control.lua:657: attempt to index a nil value
stack traceback:
WellPlanner/control.lua657: in function 'on_selected_area'
WellPlanner/control.lua1221: in function
<WellPlanner/control.lua:1219>

I selected a stone deposit and assumed it would have either done nothing or stated "No Oil Found" or something like that.

New version up. Does the error still happen? If so I will take a look.
