A new update for Monster Hunter World recently arrived. Capcom launched the patch late last week on both PS4 (version 1.05) and Xbox One (1.0.0.10), and it resolves some of the issues that have plagued the multiplayer experience. It also makes some balance changes--hopefully you weren't too reliant on Slicing ammo.
