Description of issue:

Send "Error while deserializing minecraft:xxxxx" spam to the game log xxxx can be displayed as _snowpile, _sprucetree, _icepile, _sprucetree, _haypile, cactus, _normaltree, _plainflower and many more

Then the server will have a huge lag, but the value of TPS is always 20

How did you generate your world? You have blocks whos names aren't in the game...

Redlnn commented 4 years ago

My world was upgraded from Paper-236 with --forceUpgrade

https://bugs.mojang.com/browse/MC-167027

electronicboy commented 4 years ago

Had a quick look, basically; Mojang have dropped some generation features in 1.15, however; They've not actually pulled those out of chunk data as it's converted, thus leading to these warnings as these chunks are loaded

claudio4 commented 4 years ago

Same problem even after deleting the worlds folders and regenerating them.

R4z0rX commented 4 years ago

Same here with latest build of Paper 1.15.2 (# 118). The world was previously generated with 1.14.4.

I'm getting this too:

Panderine commented 4 years ago

I'm having this too. Is this a real issue regarding gameplay? This is a 1.14.4 generated world updated to 1.15.2 always using papermc.

sannielollie commented 4 years ago

Same issue aswell - i dont know if and if yes - how far it is breaking the game. A world reset is really not a option. https://pastebin.com/zScRFf1q

Im using ConsoleSpamFix plugin now to "hide" the Error while deserializing message in my console and logfiles, so they wont get bigger than they already are..

aikar commented 4 years ago

This was a vanilla data conversion issue for 1.14. Since we are well into 1.15 now, and I believe the issue is primarily log spam, just going to close, as trying to touch Data fixers is a scary thing...

Do as @sannielollie suggested and use a log filtering plugin.
