Connectors stopped working
I created a ship. Gases and ores moved freely inside its blocks. Suddenly, the blocks stopped interacting with each other. It became impossible to move gases and ore. A connector that was glowing white turned red.
Now, when I connect a hydrogen generator to any cockpit, they do not connect - that is, hydrogen does not move between them. Also, for example, the hydrogen generator and the hydrogen tank stopped connecting to each other.
