Well It doesn't tell you that it's updated so if you've been working in HL2 mode (like I have) it comes up with a fatal error and yells at you alot. You have to set it up in a certain way to get around that, but that's only if you want to make a HL2 map. When you load it in TF2 mode, the camra shows all these weird little gold-ish shines through out the map, I don't know what those are and haven't been working long enough to know what causes it.
I'm still messing around with things to see if anything else is wrong. I litterally just openned when I saw this thread.
*tests map*
Hrmm.. when I test the map, there's it didn't start where the start point is place and I could only runaround for about 10 seconds before it closes.. though that is probably my fault some how heh.
