[media]Probably you have an item (bow) in your hand, which is removed or I think it has a minor visual bug, when the bow not displaying in F5 view.
Confirmed Trident for 1.14.3
[media]It seems this not happens anymore in the 1.14 dev. version.
Oh, I forgot the color code, but it doesn't work either.
I tried to get the scoreboard group with a packet, but I don't come to see how.
I have restarted the game, but it did not improve.
Yes, similar.
I've already done running a debug (crash viewer) but did not make any errors.
That was good. But I do not want to exemplify a player having half health, just updating the server and the player dies. I've changed the damage to 0.1, but I do not want to.
It's true, but I also reported to Spigot, but this mistake says they are a Minecraft problem.
This is not modified because it only works with one code on a server.
Coordinates, unfortunately, can not say because I have already erased the world permanently. This error is only very rarely used to foam.
Okay, then nothing.
This biome problem is repeated after about 500 blocks of distance.
No, it was not.

Then something else.
I don't think we should get rid of those particles, without it the cats will looks like a "floating cat" or some ufo. It is much better with particles. But if you really want to not see that particles, just disable the above mentioned option(s) in your client settings.
