Hi, looks like a engine-level crash got incurred on the server I ran. I am not quite sure but from the log it looks like its related to this mod. The server and all clients crashed at the same time.
Here is the log from the server. Sorry, I dont have more log history and clients' logs.
It says "dispatching event on_tick (ID 0), script mod-platform-construction-only-no-construction-robots"
