Snapshot 19w08b Server Crash - /give bad_Omen + time set night

Not sure this is new! But it is the first time we are attempting to trigger a raid with the command /give effect and we are crashing when it is applied to more than one person. Maybe this isn't a bug? Dunno!

I gave the effect to all three of us playing, and the server crashed. This log is a third crash, after running the command again, and then setting it to night to allow the players to set their bedspawn.
