I haven't patched yet, but regarding the now deleted (I don't know why) post on the map txt files in the yakesha upgrade, I took the points he put in his post and created a jpg file, it appears to be 1/4th of the zone, I think it's just mirrored (the zone was arena) but I have no idea what the other variables in the txt file are, any ideas would be appreciated.
For those interested, here is the image I created:

And for those more interested, here is the script I created:
