A have no idea how to complete todays Prestige mission. I'm at the 2nd level's Research station and the gate is not opening at the top part so I'm stucked.
I killed everything and I made to disappear all the blocks and plants on the level, nowhere a button what is opening that gate.
What now?
Not sure which one you're referring to as I haven't logged on today, but I'll take a shot in the dark and assume it's the one involving slimes and Rock Salt. For that, there should be a pile of salt that's sparkling, inspect/click on that to open the gate.
