Ok, I made this effect: http://www.youtube.com/audio?v=UKBSv_SwPGk&video_referrer=watch&feature=mhsn
I wanted to turn off the rain, because it uses the Storm Call weather change script, but when I turned it off it has an usual effect: The lightning bolts that come down would stay there forever (although barley visible). Keeping it so it changes the weather to rain makes the lighting disappear just like it's supposed too. I can't figure out how this it's related, and what is causing it.


In theory (I haven't tested it), you should get the same problem if you kept the weather clear for Storm Call. (Bolts would be harder to find though as they'd be much more spread out)
