This looks incomplete, it stops as soon as it starts loading the base scripts.
Here's what you can try. Delete particle_LargeMagicBuild.zip, particle_Casualbuild.zip, particle_SciFibuild.zip, and particle_weatherbuild.zip in your add-ons folder. If particle_MagicBuild is in there (although I specifically said to delete it in the main post) then you might want to delete that too. Then go in /blockland/saves/bedroom and delete the demo CASUAL, demo SCI FI, and demo WEATHER files. If blockland still crashes after all that, basically deleting all the files I posted, then hooray, it's something else.
I might want to add that emitters can't crash the game easily, if even at all. I would have needed to really really forget them up. Actually that's kind of a challenge, I'll try to see if it's even humanely possible to crash BL with emitters.
On topic: Started working on Cloud emitters to go with the weather. Lance is making some really nice particle decals for me so I'll also implement thunderstorms and stuff. Hail is also in the makings, and of course I'm working on the current particles and also expanding Sci Fi and Casual whenever new ides pop up.
