Zombies that do not despawn and give lag, because they collect glow ink from glow squids in the caves.

The problem is simple, because of the new glow squid can appear in a lot of places in the caves, most of the time they die and drop glow ink. The problem is when zombies with "can pick up loot" take those glow inks and they start acumulating because them dont despawn and dont count as part of the mobcap. Due to this, a large number of entities can be generated in the caves that will constantly generate lag and can crash your game.
