Server & Client Desync with falling block entities

[StimzRx]

Im unable to replicate/debug this myself as it starts happening randomly, but ive got a server with the only two mods being Lithium and Carpet. After the server has been up for awhile(unsure how long, as it happens seemingly randomly), any time a falling block lands it creates a duplicate block client-side. So that when the now-landed-block is broken there is a left over ghost block client-side until the client rejoins the server. Is it possible that Carpet is causing it? I cant find any Lithium mixins relating to falling block entities from my admittedly quick search through its GitHub.

Any advice/tips?
