Hey uffjohn, thanks for detailed report. I've found a problem with the way There is my ghost destroys entities, and DiscoScience 0.0.7 handles this situation with a warning instead of a fatal error. I've also reported the issue to the mod author so they can increase compatibility with other mods: https://mods.factorio.com/mod/there-is-my-ghost/discussion/5ca3db538a66ee000c2ae1e2
Thanks again, and I'm glad you're enjoying the mod!
