In mod version 1.0.70, deconstructing the rocket silo just after rocket launch (before it explodes) causes the mod to crash. Specifically in multiplayer, where one player stays on lignumis while the other heads to Nauvis.
Transcribing the error by hand, hopefully I don't make any typos:
Error while running event lignumis::on_nth_tick(1021438)
LuaEntity API call when LuaEntity was invalid.
stack traceback:
