I just play on peaceful mode for casual playing.

Sometimes when i need strings or bones i switch to Normal.

Today i was on desert and i was searching for Desert Temples then something hurt me and gave me Hunger effect.

I think it was Husk but invisible.

I tried to kill it but I just can't!

I typed /effect give @e glowing and only some creepers were affected but something still hurts me and gives me Hunger.

I Switched to peaceful again and again to normal but they are still like that!

i restarted the game and still like that! 

Help me
