So In my survival world with a friend on Minehut, I decided to venture out into areas we have not loaded the chunks in before in order to get deepslate and other 1.17 blocks. However, it seems as if the world is still stuck in 1.16. I can join in 1.17 and everything. I tried to craft candles as well and it is as if the recipe doesn't exist. I am confused and maybe there is something I need to do in order to update the world?
