Fantastic! Thanks

I am having a similar problem with my completely new 1.17 world. I run a multiplayer server. Normally there's an average of 3 of us on. When going through nether/end portals and loading new chucks sometimes the world caps out the RAM (2Gb) and freezes. When I installed a clear lag datapack (kills extra mobs and such on a cycle) it ran better but wasn't perfect. This update seems to generate a much higher amount of lag than previous versions. 1.16.x all ran smoothly on 2Gb in the past.

Edit: This isn't a client side issue -  MC-219639 does not describe my issue

Unfortunately, its been about a week since this happened so I can't give you a definite answer. Things have been moved around so I can't tell if the emeralds remained or disappeared. 

Despite this, a server-client desync does make more sense than dup'ing because it's a frequent occurrence in the realm. On other occasions, items sometimes "disappear" until we relog (i.e. boats or items in the player's inventory).

Is there any other info that you guys need from me?

😃

Except that hoppers don't push items into the chest that fast. It's a slow process.
