Thanks to a couple of the regulars on QMap, a rather large bug has been found and fixed in TyrLite. It affects any map compiled with "-nominlimit". It would cause all the lights cast to be double brightness. That's the only real change, so don't bother updating if you don't use "-nominlimit".
As for the qbsp stuff... well, don't ask. I'm leaving it alone for a while because it was getting on my nerves and I was having no fun. The map you've seen in my screenshots previously will still get finished eventually, but I'm probably going to start another one first because that one has gotten quite stale in my head. I need to come back to it later with a fresh prespective.
