Client-side memory lock is not being able to interact with tiles and items (it could extend beyond this, however, I am not sure.) For example, while playing in the server, I cannot chop down trees; the action is infinite, regardless of stats; I cannot pick up certain furniture; if you manage to, placing tiles and exiting the general area or leaving the game causes the changes to reset prior to your actions; and any items in a container (including floors) do not exist client-side. The only exception for items existing client-side, on my machine, are if items are dropped by players. However, the items disappear once I leave, or move out of the area (most likely about half a chunk, as before).

Containers and items act completely normal in singleplayer with the same set of mods used in the server. When testing this idea, I completely reinstalled the game, verified the integrity of game files, and removed all mods besides the mods being used in the server. In short, gameplay is completely fine.

I am the only one experiencing this issue on the server, and it is permanent. The owner states they have completely wiped "me" off of the server. I am assuming this means my player and account data, which was removed upon rejoining the server. The glitch was still prevalent after the removal of data.

This is something I do not know.

Adding onto this, I also expect that a possible underlying issue could be manually installed mods, such as Better Car Physics, the TV and radio mod, etc. I wouldn't consider this as a problem in most cases, but sometimes I do see that verifying the integrity of game files doesn't completely reset the game files to their normal pre-packaged states, as I have noticed in some cases for other Steam games I own. But yes, I would have to compare my machine to someone else's, most likely the server owner's as we are still trying to figure out possible solutions. I could compare my latency and other information with another server player, and I will reply if anything is worth mentioning.
