I guess you have implemented new “features” which screw with the game when internet connectivity drops in and out?
This morning on my train into work, I started a stage with 4G signal. Completed it whilst I was in a signal black spot, did a couple of bits in my town waiting for the signal to come back and start next stage, and when it did I was still on the previous stage. And missing the energy. Also happened whilst on the tube, picking up WiFi at stations and completing stages in the tunnels where there is no WiFi.
Never used to be a problem before this new update
I have no issues if the only way you can stop exploits is to require internet connectivity every waking second we are playing the game, but stop punishing honest players.
