There is a file in the save folder called telpstates.000 which keeps track of the teleporter pads' status. Somehow the teleporter pads all got disabled, and presumably could not be re-enabled because another part of the save had them listed as already enabled (perhaps the story files).
In any case here is the
telpstates.000 file (1KB) from my save just before hitting the gong, with all teleporter pads activated. Extract the zip file into your latest save and you will be able to teleport to the council hall.
This file is quite small, and with a bit of trial and error it would be easy to figure out which values correspond to which teleporter pads, but replacing the whole file is faster.
A belated welcome to the forum.
If anyone else runs into this problem earlier in the game and doesn't want to enable all teleporter pads, I have all my old saves, so could grab a file from an appropriate place, or figure out which teleporter pads correspond to which values in the file.
