Universal cable bug

[xhaooy]

Issue description

Hello, a few times this error from screen occurred (the power stays in one cable and won't go to the other), after server restart it all goes back to normal. Its not chunk boundary related (see attached screenshots). If i would break the not-powered one it will remove the power from the one before (or after). There are no errors in server logs.

Steps to reproduce

1. Start a server
2. Play for a while
3. Wait a few hours (can happen while still playing) or days
4. There is this bug

That's a lot of mods, we'd need to narrow the list down.

I'm also not wanting to debug it with things like Concurrent Chunk Management Engine and Forgified Fabric

[xhaooy]

i removed them from server and client (Forgified Fabric is an api so i delated related mods as well). also i updated all the mods and neoforge to 114

[xhaooy]

todays testing: this issue appeard after around 30-40 mins. i teleported to my induction matrix and back to my base and this time that fixed it (check screenshot, around 276 meters)

Do you have any "performance" mods still installed?
Or any fabric mods still?
