Read a blueprint and generate a set of combinators containing the item signals and counts.
This mod dynamically adjusts the research speed and productivity based on the current count of online players. It allows to slow down or even stop the research in case none or only a few players are online.
This mod will pause the game when the last player disconnects from the server. So the first player joining again can download the complete map and does not need to catch up. To resume he just needs to push the "unpause" button.
