@Caelte Level 14 Should end as blue, not yellow. There's more than likely a bit of another color under one of the buttons of the UI, I had the same thing happen on 14.
Suggestion for high level upgrades:
1) Two upgrades that reduce the mana regen loss from auto casting first to only 25%, then no loss. These would need to be VERY expensive to be balanced, but would be nice to shoot for at "end game".
2) Additional Assistant unlocks for 200/300/400/500 etc. of each building.
3) Increased upgrades past 200 of each building, thinking 300/400/500/1000/1500/2000/2500/5000/7500/10000.
4) Upgrades for having X of every building. So if you have 10/25/50/100/etc of EVERY building at once it unlocks. Would give incentive to keep buying buildings that arent your races focus.
Love the game, one of the best idle games in quite some time =)
