Eek. That sounds like I've messed up something on multiplayer code, it's a bit hard to test this stuff. I would need to recreate the issue, or at least see an error log from Factorio.
I have had the same problem. I love this mod. its amazing. And its hard to get the astroid outposts before late game which makes it even better. The only problem is that I cant use it on multiplayer. And I basically only play on multiplayer. if someone is on the map with you, this error occurs for me.
