Projectile and Summon Disappearing
When we do a multiplayer modded world, when projectiles hit a boss they just vanish, except for the host. We use host and play, and this has been tried with both calamity and thorium. When (most) summons hit a boss, they despawn and vanish completely. Certain weapons, like Healer's scythe or templar's judgement disappear completely when hitting the boss.
