Light map generation is demanding
 
This is almost an entire day's worth of light map generation.  It is very demanding on the CPU, almost purely on the CPU.

As a general update, I've nearly finished the first run of proofreading where act 14 needs a rewrite for 2 parts of it, perhaps an extension.  I'm currently working on the appendix and there are 7 in total, a lot of which copied from 10EM, but there are some differences.  The 2 most notable differences are the inclusion of the list of equipment and the bestiary, where each monster is detailed.
