Item/Board Switch, All Unusable

The strangest bug. Late in the game, 3 players left, when out of nowhere mine and another players unused items and generators switched. So, during planning phase, I had his items and generators, on the wrong side of my board. All the items had a gold outline, and could not be used or moved. They switched back when we battled, but still remained outlined and could not be used. Pretty aggravating in the final stages of a ranked.
