Do you have any previous saves that you can reload, at least to check if the teleporter pads are working, or not? If they are disabled in a save where they were previously working, then the problem may be with the game itself, in which case you could try deleting the files in the dynamics folder, or even backup the saves and reinstall the game. If old saves still work fine, then the problem is more likely in the save itself.
The '
..\Divine Divinity\Run\Dynamic' folder is used as a cache for the game. Files are created / copied there from the save game folder when you load, and written / copied from that folder when you save a game. The files will be re-created as required the next time you start Divinity. If there was a corrupt file in that folder, deleting the files should fix the problem.
Troubleshooting Tips (& manual install procedure)There are a couple ways you can get back into the council hall;
You can leave one teleporter stone on the ground somewhere, keep one with you, save the game and then
hex teleport into the council hall. From there, drop a teleporter stone, use it to get out again (after scrying, or whatever), pick up the teleporter stone outside, and carry it with you to drop and use whenever you need to get back.
Alternately, you can use the procedure in the topic
FIX for the Missing Catacombs Portal to temporarily get into the council hall, long enough to drop a teleporter stone there.
