IIRC the bug is actually only cosmetic . Actual upgrades are called Chrono 05 , 15 , 25 , 35 , 45 all five if them . Baldurans probably wanted the upgrade button to show the current level of the upgrade instead of the next one , and that led to him having to create the last , sixth , upgrade just for the sake of displaying 55 after all five were bought . So it is not buyable , but the price is erroneously still displayed . This is from recollection , I didn ' t check the source code for quite some time <| sep |> So drain the swamp in progress <| sep |> What did marchand get ? <| sep |> How did you get the leaks ? <| sep |> That I didn ' t go to see my grandfater the time before he passed . When I did go I heard his last breath . It still kills me inside that I was selfish the time before .
