Minecraft 1.20.1-forge 47.4.2
TSSM 1.7.0

When I put a inventory proxy, nothing happens, and it can work correctly. But when I walk away, quit the game or server, the chunk with proxy will become an empty chunk like this:

The chunk with proxy will go wrong. I cannot go into it, and entities inside are seemed to glitch too. Chunks arround cannot be rendered. But all the machines (like TSSM's terminals, Create's machines, Vanilla furnaces etc.) can work correctly. I can even open the terminal inside the glitch chunk with wireless terminal and I/O items.
