I started an exploration when the offer was on for 1 worker. When my upgrade of an oil well finished after the dock deal finished it sent my 3 workers to join the 3 explorations already in progress. I have no idea how these 3 workers swam to meet the boat and the time of exploration has gone up. Did anyone already on an exploration when the deal started on September 1 get their workers to swim home and half the time of already started explorations
