i was disconnected when today's news was posted. upon reconnect, my watchtower, workshop and a farm slot are gone or no longer accessible by clicking on them. I have cleared history and reloaded several times to no avail.

I have experienced similar at least once in the past. It cleared itself up by itself within a day (or two?). No clearing of cache or anything else was necessary or performed.

It was clearly a game / their end (temporary) bug - otherwise it would have been displaying everything, or nothing. Not this in-between version you are experiencing.
