Small glitch I found?
So, I went and tried to do an Energon Grimlock level (failed due to carelessness with mortar towers). So I went and recharged him.
While he was recharging, I went and did an Ultimate Megatron level.
After that, the Energon Grimlock level was replaced by a Soundwave level, and an Ultimate Optimus Prime level I had was replaced with another Ultimate Megatron level.
Is it supposed to change like this, or is this a glitch of some kind?
