[Bug]: Dragon spamming the log

[Groupix05]

What happened?

I dont know if its due to Ice and Fire or not, but here's my problem :
Ice and Fire is spamming the console on my server with :

[16Jan2024 23:27:29.529] [Server thread/WARN] [net.minecraft.world.level.entity.PersistentEntitySectionManager/]: UUID of added entity already exists: EntityDragonPart['Dragon Part'/2056, l='ServerLevel[world]', x=207.17, y=2.42, z=3331.52]

If I tp to 207 2 3331 I found this electric dragon :

The dragon fly, sleep and attack normally but he is spamming the log.

I was using versions on github before this one but I didnt do a lot of testing because they were rare to found.
But the electric dragon at the surface was not spamming the log.

Minecraft Version

1.20.1

Ice and Fire version

iceandfire-2.1.13-1.20.1-beta-2

Citadel version

citadel-2.4.9-1.20.1

Relevant log output

Too long to be put here.

Other Information

• I am using other mods besides Ice and Fire
• I have attached a log file from the session that I have experienced this issue

[SiverDX]

for now you can use https://www.curseforge.com/minecraft/mc-mods/deuf-duplicate-entity-uuid-fix
(not sure if there is even a fix for this tbh)

[Groupix05]

This mod is already installed ,check line 243 in my log file

[SiverDX]

it's apparently a vanilla bug
saw this in the mods comments

some people fixed it by teleporting to the location and then logging out / stopping the server
others by killing the entity

iceandfire doesn't do anything special with uuids and the bug could be caused more often by specific mods i'd imagine
if the chunk thing is true i could imagine dragons being more prone to this (due to their size), personally i have yet to encounter this issue

[DigitalWendigo]

Same here on the 1.19.2 version of the mod, newest beta release.
Log goes from roughly 400 bytes to 1,700+ bytes within minutes, all spams regarding uuid's and dragon 'parts'.
I've downloaded the uuid fix mod and will see if it resurfaces again tomorrow, when I get the chance to test it.

[DigitalWendigo]

Seems to also happen with CyclopsEye.

Edit:
Installing the UUID fix mod (DEUF) does not resolve the issue, and it seems to happen at random.

@lukaskabc can you try with this version

[lukaskabc]

I'll try and let you know if it happens again

[SiverDX]

if it doesn't happen again you can still check the log (the error should appear at least once if the fix triggered) and post that

and this one

[lukaskabc]

iceandfire-2.1.13-1.20.1.zip

and this one

Dragons have been discarded and deleted (yes, even the tamed ones, which is not great at all.).
Sending logs below, unfortunately, normal logs were lost due to server kill, but debug log is complete.

logs.zip

[SiverDX]

removed the part which would mark the part as removed
so either the uuid actually gets updated and the entity gets added or there is some other mod interfering

discard still happens but it logs a summon command for the dragon (incl. age, variant etc.)

I had the ame issue. I start the server and it crash with the last mod you upload.
