Crash on Teleport

[CrossVas]

Describe the bug

The world is crashing when teleporting to my base.

To Reproduce

1. Make a teleport at your base (I use mekanism teleport);
2. forceload the chunk where you have a mid-game base and ae system (interfaces, buses, controllers, cables);
3. Go far away from your base and set another teleporter to your base;
4. Teleport to your base using teleports.

Expected behavior

Load my base and not crashing.

Environment

• Environment:
  Minecraft: 1.16.5
  AE: 8.3.0-alpha.1

!!! Also tried with 8.2.0 release build: works fine.
Maybe I should reorganize my cables. I feel like I'm missing something, but the fact that previous version worked fine makes me think that this is not related to my way of cable management.

F3+C crashlog: pastebin;

Spoilers:

First picture: my base from top. I have a multiblock controller, another controller which take channels from the multiblock and spread it around the base.

Second picture: the chunk where I'm teleporting - floor 1

Third picture: same chunk - floor -1. Also the way I use p2p to get channels

4th picture: same chunk - some cable-management (2 p2p tunnels, 2 dense smart cables going to my storage room).

There is a bug which causes clientside tile entities to be exposed to the serverside when playing in single player.
