Except... they didn't. I can still hear them mooing and baaing and... whatever llamas do. I can't hit them with my sword (nothing happens, it's like they're not there), but bows can hit them (and they drop loot as normal). Anyone know what's going on or how to fix it? I'm on a Spigot server running Minecraft Java 1.14.4 on a MacBook.
(Also, I can't see illagers, but pillagers can see and shoot me.)
