We didn't, NVIDIA caused that bug due to a change in their drivers, long after Gamma was released. How were we supposed to guess they would do that and add something to fix it before it happened? Scripts 4.0 has since been updated to work around the problem, so TS:Reborn and, in fact, any future versions of RA:APB will work without the control panel fix.
We have capacity for up to three official servers, we'll load up more servers based on demand. I'm not sure if the server pack will be available on day one, but it'll certainly be available shortly thereafter if not. I'll probably be putting together an installer for that.
The new launcher, which will ship with Reborn, gets it's server listing from an XML file on the BHP backend. This file is currently updated manually with new servers, so anyone who would like their server listing can contact me to have it added. In future we'll be setting up a plugin that'll talk to the backend and add servers when they are live (and remove them when they are dead)
Yes.
