Years?
No. The development team has stated repeatedly throughout Patreon & Discord that the removed content is not permanently removed and is coming back in a subsequent update. As we speak, they're working hard to bring back the missing content in the next update.
A lot of the work has gone into the back-end of the game to ensure seamless updates can be made faster and more efficiently for the future, and while a lot of developers on this forum know that, releasing without "front-end" content is almost like cutting off ones foot to buy new shoes, it's something necessary in order to future-proof the project and ensure an actual running project that works on a wide variety of hardware, something not easy considering a large percentage of players are varied from 10' series GPU's right up to 40's etc.
In essence, all I can say on behalf of the development team is this - the game is being worked on, we're hearing what people are saying and we're listening - we understand that not every update is going to be to every individual liking, but that's the way it sometimes goes. Development is not a simple "click-add-release" methodology, it's a process - and sometimes, updates can appear "empty" despite a lot of work being done on the back-end.
The upcoming features & updates are coming, and they're planned for shorter release cycles. When there is more information, I'll be glad to share - but keep the feedback coming, everything people are saying is being documented so that we can ensure improvements are made along the way.
We want to ensure that COB can truly live up to its full potential!
