Previously I couldn't use shield regardless of how many times i crouch if i had trident equipped, but after many log-ins and outs of my world, i was able to use my shield, but then melee attacks stopped working. I am unable to break any block or use any tool or item that requires left clicking. The trident ranged attack is the only one working. The pickaxe, axe, even the sword is basically useless. I cant even break the blocks by just hand. The game has become much harder since I cant break any block or kill any mobs anymore unless using trident ranged attack.
