Not really a bug more of an issue (to me anyway, might not be to others) and sorry if you've already been asked this question but, will the 'only properly rendering seven lights' at a time ever be changed/fixed? Or even made an option such as 'render x amount of lights'? Once again sorry if you've already been asked this but I looked and it doesn't seem that you have in this topic anyway.
I'm assuming this isn't the 'point lights' things but I could be wrong. : \
