@pako
I have been upgrading the coneheads since I’ve got them. Everything was going smooth and steady until I reached level 13 with the last one of them. I had to spend a day, more or less, playing to get the crystals I was missing to upgrade it to level 14. Now, I am on another hiatus to gather up crystals again, this time round it’ll take longer, as I had depleted my stash. Now, I see your point @papakarlo.
