Does Mining Layers work in multiplayer?

Honest answer: we do not know.

Mining Layers has never been tested in multiplayer. There is feedback from one server, but without a log — and without a log that is not something we will make claims on.

The decision behind it was deliberate: multiplayer comes once the mod is content-complete in single player. Foundation first, then doubling the number of failure sources.

If you play on a server and try it: a server log helps us more than any description. Post it here — this is the biggest open spot we currently have.
