Hello, I run a server with "Space Age Hard Mode " modpack which requires this mod. Today we noticed that circuit wires connected to foundrys making iron or copper plates from molten liquids will be automatically removed. Besides that, players cannot join the server (by the desyc problem), after those wires got removed, though players already in the server wont be kicked out.

Thanks for your feedback, Could you explain in more detail how you managed to get the circuit wires to be removed, so far i could not reproduce it.

Also i have no means of doing multiplayer testing, so if anyone has any pointers how to address that issue, ill be happy adapt the code.

Newly placed fountries without any recipe selected are SA's original fountry. Foundries with molten recipes selected will be replaced by "fountry-molten". So if you connect a original fountry with something, then set its recipe, the entity will be replaced and the circuit will be removed.

I personally believe the code replacing entity triggered something that caused the desync problem.

For multiplayer testing, a quick solution might be downloading additional factorio clients, they can run at the same time on the same PC. Use one client to host (LAN, dont select verifying user identity) and another one (dont sign in, use a different random ID) to join.
