You are right, when connecting all the way, servers are moved to the top. However, the bug itself remains, only the cause must be another then. I tested again, actually connecting to Starfusion this time, then quit and selected Absurd-IRC. Result:
* Connecting to irc.absurd-irc.net (6666)
-
* Unable to connect to server (Connection refused)
-
* Connecting to irc.absurd-irc.net (6665)
-
* Unable to connect to server (Connection refused)
Clearly it's attempting to use the ports of the previous server for the 2nd connection, which are not available for Absurd-IRC.
As for the other bug regarding the recent servers list, this stays reproducible when connecting all the way as well.
