They done a Code restructure not too long ago, to reduce the mess it had during the years, now if its a mess again its their fault, if i recall was Main coder and they hired a freelance to help recode most of the critical parts of game aswell some other things.
He could hire someone else to help, but at this point he wont, to not make any work conflict that can lead to delay of the tech update, but also he doesnt hire anyone else cause the money reduced from Feb 2022 to Feb 2023, which was a significant lose, you might say that makes no difference but it does, money drops = quality and development goes down.
