When the provisional rocket silo is ready (2.1.14 with Lignumis 2.4.1) or is launched (2.0.77 with Lignumis 1.10.2), the game crashes. I attached screenshots, the logs, the dump and a save. It's enough to enable only Lignumis with its dependencies and then load the save without other mods. Make sure the rocket silo is placed fresh and wait for the rocket to be ready.
