We have a problem over at Brierie multiplayer StarMade server regarding blueprints.
It seems that when we reach a certain critical mass of catalog blueprints, players are no longer able to join the game. Specifically, they can join the game, but they are unable to spawn into their sectors (they become stuck at "waiting to spawn").
Clearing all the catalog blueprints fixes the issue, but this results in further problems - partially filled blueprint items for example, will no longer spawn due to the catalog blueprint being removed.
At the moment we have to clear out the blueprints approximately every week or so, as the problem will completely prevent some (but not all) players from spawning into the game.
I have copies of the serverlog (but not starmadelog, unfortunately - those roll over every few hours) if that would be any help.
