I'm currently playing Resoln and am at war with Pariden. Last turn, I conquered an Outpost in the north-west. It had a Fire Shrine in it's ZoC, which got destroyed when I ended the turn. Now, when I click on the Shard, my city of Blackstead gets selected instead. If I click again, the Shard gets selected, but I can't build a Resoln Fire Altar. Clicking on the 'Build'-button does nothing. Quitting the game and loading the save did not help.
Here is the savegame.
