Can't place Nuclaire chamber on my server

[Thyvo]

For some reason, I cant place a reactor chamber in the world, its placed and instandly removed, is this a bug, or a feature you have to enable on the server?

also, is there a way to detect the heat level of a reactor in multiplayer?

I think you have to place the actual generator first before you can place any chamber blocks.

You can only place chambers if they are attached to reactors, yes. You may need to put down a piece of dirt or something, put the reactor on the dirt, then remove the dirt and attach all six chambers.
