Entity Loss/Duplicate UUID

[fubieslc]

What behaviour is expected:

For this not to happen I guess lol, is there a way I can disable this or something so entites stop despawning?

What behaviour is observed:

I'm getting a bunch of duplicate id errors, I tried putting the uuid-resolver setting to saferegen but it didn't help much. Lots of entities are coming up missing lately too, animals, item frames, maps in item frames etc.

duplicate-uuid-resolver set to "warn" or decrease duplicate-uuid-saferegen-delete-range (from here )

Saferegen is the default setting

See #1223 for info

That patch was dropped in 1.14, however needs to be restored;

This is still an issue in craftbukkit, just the warnings are actually disabled making it seem like this isn't actually occurring

Should be fixed in 1.14.2: https://bugs.mojang.com/browse/MC-150170?focusedCommentId=547891&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-547891
