Hi, has anyone faced the issue when placing a boat on another one causes the top boat to slide off on 1.21 fabric servers?

Its kinda hard to explain so heres a video of it happening, this only happens when the chunk is not loaded for a while (ex. leaving server and opening a single player world for abt 4 minutes, then rejoining server) or sometimes when the server reboots: https://cdn.discordapp.com/attachments/699511817696706642/1262918035682103296/Untitled.mov?ex=66985793&is=66970613&hm=2b249e800312199f8fe5bd85bb3efa7cf871d4773b05dda76c5bb4341fe4dfde&

the boats are stacked like this...

these are the only mods server side

This farm is based on this design by Rays works: https://www.youtube.com/watch?v=sT4noYO1xUE&

Does this appear like that in a vanilla client as well?

YES! it seems it does the same thing on vanilla as well. But only for servers tho since it works fine in single player

Ah yes, typical server-client desync. :mojank:
