Describe the bug

turning a powered spatial anchor into a create contraption crashes the server

any other ae2 blocks I tried worked without problems, including spatial anchors which aren't powered

How to reproduce the bug

1. build a create contraption, e.g. with a minecart
2. put a spatial anchor next to a creative cell on the contraption
3. assemble the contraption
4. server crashes

Expected behavior

the server shouldn't crash

Additional details

this could very well be a create issue, I am posting it here anyways since it is the only ae2 block that crashes (every other block just works)
issue on create issue tracker: Creators-of-Create/Create#2953

Which minecraft version are you using?

1.18

On which mod loaders does it happen?

Forge
