Artaxes the Lion and Fire Pheonix seem to be the two Crusaders causing the Upgrade All freeze. Switch them out for different Event Crusaders or send them on missions to work around this issue.
It always amuses me when the buffs for the weekend are so obviously based on the northern hemisphere. Yesterday where I live it was 38 degrees C (100 F), so it it's pretty funny when the buff talks about it "getting chilly".
Lol, I nearly fell off my chair when I leveled up a crusader and they bragged about how strong they were! Is this a new feature or an April Fool's Day joke?
Some feedback: I find the "Get me Out of Here" objective to be the worst one in the game, due to the length of the objective and the very low margin for error. I think it would be better if you either reduced the level depth (to about 50?) or relaxed the time limit (by 10 minutes), because right now it's not fun, just exceptionally annoying. Apparently mobile users have it even worse.
Annnd... completed. The only time I needed to use a walkthrough was for the fishook through a mirror thing (Broom + hanger). Great game, faved and rated 5/5!
I think I've played too much Crusaders. I was voting in the Australian Election and all I could think about was "Who would make a better event crusader?"
