I saw I kind of bug in the game. Sometimes, I build a structure and the prices of all bulidings increases a lot. Ex: built about 100 altars, and the prices of market increased from about million to about billions. Refreshing page solve the case, but I dont know if this bug are affective single builts too.
Well... without the energy system, I decided to stop playing this game. This change is good for enjoy more the game, but there's a risk to players of stop enjoying other things, hehe.
 "Idle Conquest"){kind=icon}
 "Doom Forge"){kind=icon}
This is probably because you selected buy 100, or buy 50. when you refresh it goes back to normal because the game loads with buy 1 defaulted.
