Odd behavior by bots in Co-op battle in Okinawa Domination. During one battle, Kurfurst bot ran aground, then backed up and ran aground again in the same position. Continued this behavior for several cycles. Was still doing it when battle ended. This was in the northeast corner of E6 heading southwest. Found this about 3 different times. Another battleship and a cruiser exhibiting same behavior. Also, tried to collect containers earned by XP. Selected "Collect container/Try your luck/Yes' and got "Transaction error - Transaction processing error. Please try again later.' This occurred several times.
