Twas a joke sir really its personal preference and so I don't have to sell things one by one to know what I have and what to get rid of and overall faster maintenance on making sure my budget is I profit knowing even a little about coding knows it would be a small effort to add a remove all button just pass it along like you do everything else.
My lab from the upgrades tab says its getting +10% to combination then when I go to the lab to combine something it says +3.5% from lab so which is it? Also the vip function one level 1 says I can to levy twice a day as apposed to just one but its still making me pay gold for the second its a good thing I didn't put a lot of money into this game but I figured I'd post this to warn other players about spending their money in this game.
