Found a bug; trying to pick a spell during insatiable hunger 2, causes an automatic fail for the challenge, yet it says nothing about spells being against the challenge rules.
So the currency change appears to be as meaningless as an inflatation setback in a single user economy. Changing all previously owned items into a locked label to prevent upgrading them. An inventory limit, ontop of upping the cost to salvage items to upgrade. Oh don't forget that the campain is still handicapped like a cheap facebook game by an arbitrary fuel system; so we're still gimped on how much and how fast we can upgrade items, besides all previously used items being next to useless now. The cash-grab has strangled all remaining enjoyment for this game.
Found a bug with the event.
It says that you continue to grow the orbs while idle or offline; however if you leave the page open and put your computer into sleep mode or otherwise some kind of powered down state, orbs stop growing. I've tested it a couple times for different amounts of time, and it's consistent.
Disappointed that such a game breaking bug pops up with such a small window to do an event; feels like the game has been steadily sliding downhill since the graphics overhaul.
Found something strange in the test area, had the AI vs itself with the same saved army. Long story short, two lilith's of opposite teams were diagonally 1 space apart with a phantasm between them; they repeatedly alternated charming the phantasm until one lost by the morale decay from too many moves.
It took nearly 3 minutes but was an amusing, just thought I'd let you know in case it's a bug.
