Plasma Pea upgrades disappear.
I have the speed upgrade for plasma pea, but I can only "see" it if I click upgrades and don't move my mouse cursor. I cannot move to another upgrade slot or it disappears. I also unlocked the ammo upgrade last night, but it doesn't show up at all in any upgrade slot. I sure love my pea, but not being able to access upgrades could make the other characters far more powerful and more worth leveling.
Did you tried scrolling up or down or using arrow key? Control are a bit buggy with the mouse right now.
