it seems like its something else(removed waila(etc.) from the mod list) the player still cant join, even though other players can join

[the chunk the player is trying to spawn in is not corrupted/broken in any way]

Try 1.16.5-36.1.25 and provide us with the logs from both sides.

I added some extra logging to make it easier to figure out what packet is being bad.

I do Forge for free, however the servers to run it arn't free, so anything is appreciated.

From what I can tell there is over 2 megabytes of advancement data being sent to the client. So far Forge only splits overly large recipe and tag packets, it seems the advancement packet needs to be added to this list as well. I will make a pull request to add it.
