In Goldsea Arena I encountered a bug when evolving one of the new chameleon companions into a three star unit. The unit switched to the back row and I was no longer able to put a unit in the spot it had been in on the active row. Any companion I put on that spot would return to the bottom row when I clicked start next round. and you could see during the fight that the slot was empty there was no companion fighting in that slot. I did not take screenshots sorry. It was late in the game and I came in second place regardless of only being able to use four units.
