1.21 Entities on Fabric server
ThexXTURBOXx opened this issue · 2 comments
My mod is running on Architectury API 13.0.1 for Minecraft 1.21 server.
Everything is working fine on NeoForge - both client and server.
However, on Fabric, I receive lots of errors regarding networking.
In this specific case, it is the NetworkManagerImpl#createAddEntityPacket function somehow misbehaving.
I have seen similar errors with other packets also. So, this seems to be some internal problem with the packet handler itself (?)
Error log

The format desired is tag.item.<namespace>.<path> for the translation key with slashes in path turned into periods.
To disable this message, set this system property in your runs: `-Dfabric-tag-conventions-v2.missingTagTranslationWarning=SILENCED`.

Dev warning - Legacy Tags detected. Please migrate your old tags to our new format that follows better conventions!
See classes under net.fabricmc.fabric.api.tag.convention.v2 package for all tags.
NOTE: Many tags have been moved around or renamed. Some new ones were added so please review the new tags.
And make sure you follow tag conventions for new tags! The convention is `c` with nouns generally being plural and adjectives being singular.
You can disable this message by this system property to your runs: `-Dfabric-tag-conventions-v1.legacyTagWarning=SILENCED`.
To see individual legacy tags found, set the system property to `-Dfabric-tag-conventions-v1.legacyTagWarning=DEV_VERBOSE` instead. Default is `DEV_SHORT`.

I can also confirm that this is an issue on 1.20.6 - NeoForge works fine, but Fabric has problems with servers.
In 1.20.1 at least, everything is working fine - both on Forge and Fabric, client and server!
Have not tested anything in between like 1.20.5!
