There are no drops after mining gold, redstone, and obsidian. I've started new games and reset everything to default, yet the problem gets worse each time. First game my problem was only with mining gold (no drops), started a new game and caused the redstone and obsidian to also have issues. Now, after fighting pillagers, I no longer get emeralds from them. All these issues are still occurring. 

YOU ARE MY HERO to anyone who can help me.
