There are currently problems with clients disconnecting and CTDs in 1.06. Lead Pursuit have a hotfix on the way but until then there is no point in testing 1.06 on-line.
The install standard will therefore remain 1.05 until the hotfix has been released and thoroughly tested by Tomb and his team.
I could be wrong but i thought that the clients disconnecting problem is only appearing while clients are connected to a host only server. This is a kind of server we are not using within our squadron on regular basis.
Several on-line Sqns are reporting disconnect and CTD issues with normal hosts as well as host only servers. I know of at least two Sqns who have switched back to 1.05 as their install standard. You can find more info on Frugal's.
