The issue isn't related to the launcher or files. The flaw itself exists in the cloak texture, specifically the original cloak texture on the Mojang server. I don't know which of the six sections my texture issue report would fit in, so I chose the launcher section. Sorry if I've confused you in any way and continue to do so.
The problem isn't with getting the cloak or how I got it, but with the texture itself. The texture itself can be obtained from the cache in the game folder (if it's been running for a while), or simply by downloading it from the internet, like on namemc.
As updated in the description, I've possibly found the cause for this lag spike in MC-132437.
To summarize, this has to do with a call to the profile service that seems to be handled poorly.
Confirmed in 1.13-pre5 server. "/effect give" disconnects everyone out of the server and it doesn't even give the effect.
Command:
/effect give @a minecraft:water_breathing 360 1 true
Message:
Internal Exception: io.netty.handler.codec.DecoderException: com.google.gson.JsonParseException: Don't know how to turn {} into a Component
Couldn't find any logs server or client side.
As per MC-125007, it seems generation fails when decorating, added screenshot where the end ship generation fails exactly where the elytra, chests and dragon head should be. (18w10a)
Can confirm, it is like that also in 18w09a, any connecting redstone away from those observers will trigger a pulse as well.
My guess is because they are supposed to swim towards treasures or ruins, I think that behavior should be changed when they are above sea level.
Can confirm
Attached my playerdata folder
I can reproduce it in every snapshot version since 17w48a. Are you sure you are using a multiplayer server?
The second possible reason why you can't reproduce is because your name doesn't have capitalization or symbols which lately seems to impact the parser a lot.
I see. A simple copy of the file to tags/items would solve it. I blame the lack of documentation. Thanks.
