I can no longer see my mechs 4-6. It shows in the items area (right) that they are equipped but cannot see them in the left window when clicking the arrow left or right.

They changed that from clicking through mech 1 - 6 to mech 1 - 3

If you want change mech 4 - 6 you have to change the mech row before

I do not understand way they changed that

Thanks, I figured it out before your reply. I agree that they should put it back they way it was.
