Hi djeZo I had a strange issue. I rented one of the rigs and it said rig is already hired. But it seems it was hired by me. Not sure what happened there. Wasted a couple of hours it seems
Maybe you hit refresh after you hired it

That would explain the situation.
This is actually what prompted my question earlier, I was worried that me deleting/recreating the rental plans screwed something up. Not sure who's fault it was or what happened, but, he paid to mine his stuff and it was mining mine instead, so I extended Zombie123's lease 3 hours.
It was still weird, and it could have just been a timing thing with deleting/recreating rental plans. I'd test to see that it won't cause issues, just to make sure.
