A proper fix is needed for collision. When you aggro 2–3 mobs and engage in combat, mobs positioned behind the first one are able to hit you through the body of the front mob. The same problem occurs when you're surrounded by buildings or objects. You can't hit mobs with slashing attacks because your strikes are blocked by the objects, causing your attack to stop. Conversely, the mobs can hit you without issue, as if the objects weren't there. This feels unrealistic for a game in 2024.
