I have been having 2 different but related issues with raids on beta worlds.

The first issue: during a raid, when any player attempts to damage any raid entity directly (via sword, bow, crossbow, or trident) it will register the first hit on the targeted mob, and then the world freezes (typically before a second hit can be registered), crashing the game shortly afterwards. This has happened on all beta worlds I have played - my own worlds and multiplayer on other beta worlds. Non player damage causing entities like golems, conduits, fire and magma do not crash the game and cause damage normally.

The second issue: I have tried multiple attempts to reload a world after a crash. Typically, worlds will reload as if I had the bad omen effect and just walked into a village, starting wave 1 of a raid. However, on occasion, the raid will not start immediately and will take roughly 1 in game day / night cycle to begin. In the ladder case, nothing seems to happen at first, but the raid begins seemingly randomly some time after - signaled only by the raid airhorn sound - regardless of where the triggering player is in relation to the village which triggered the raid.
