Just found out yesterday that the command blocks broke my world. Mojang apparently completed deleted them or something, guess that means no mods through command blocks for console after all.
You’ll have to go back to a previous title update and swap them all out for a different block and even remove them from any chests you placed them in if your save is messing up as well.
I know i’m bumping this, srry but i’m not on here much anymore. But yeah 4j removed them and also removed the ability to break blocks above the nether to allow more game save data for the new end, which absolutely makes no sense because its still using game save data on top of the nether if you place blocks. If i get some money i def switching to pc, tired of bs Microsoft and etc.
