Spatial anchor does not propagate across spatial dimension as it should after quit&load

[MageInBlack]

Describe the bug

When used in the Spatial Dimension, spatial anchor does not propagate properly across quantum bridges to load other spatial machines without the anchor. This is not the case for other dimensions (works in the nether).

How to reproduce the bug

I made 2 setups to test it for both dimensions other than overworld (spatial and the nether), and one in the overworld. Overworld is a spatial multi setup with spatial anchor that leads to 1-3 quantum rings. In spatial/nether 2-3 spaces separated by huge distance (another spatial or 10k in the nether). Setup as follows: 2-3 spaces in the same dimension connected with ow with quantum rings. One of them has spatial anchor, others don't; or 1 space that acts as a hub with 1-2 more quantum rings that lead to other spaces in the same dimension.

In the nether both setups work and load after re-entry into the singleplayer world. In spatial only the one with anchor loads. Others do not and need to be manually loaded before they are accounted and loaded by the anchor until the next exit.

Expected behavior

Anchor loads all the things on the same network in the same dimension as in the nether, as long as at least 1 machine has the anchor others don't need it and have to be a part of the network.

This is that broken? Huh. I wonder why it even happens.

I have made a 8x8 chunks spatial for further testing. It seems that spatial anchor inside the spatial does work if it propagates to neighboring chunks, but chunks 1 over do not load on restart. This also happens with ~50% chance every time i rejoin the world, might happen because i do it quickly.

The first and second one are bridges connected with overworld but 1 chunk in-between. Anchor does not load it if there is a chunk in-between them in that case. The third one is the machine in the opposite corner of 8x8 chunk machine

Another note. If I put another quantum bridge inside the spatial and connect it over 1 chunk, it works. But if i go another chunk further away, it stops working again on reload

Also attaching more photos of previous 2 setups which also do not work.

• First screenshot is the second setup in overworld.
• Second screenshot is the second setup in main spatial machine
• Third screenshot is how 2 other spatial machines look like.
• Fourth and Fifth screenshots is network in 1st setup mode
