When a volcano erupts and damages an improved tile, it causes a Pillage effect. According to the civilopedia, "Once Pillaged, an improvement may be brought back online by its owner (a builder operation that always takes one turn but does not require a builder charge). I had a mild volcano eruption that Pillaged two adjacent tiles. I marched a builder unit over to the sites, but there was no builder task icon for Repair or whatever. Just sitting on the tile for a couple turns did not automatically repair the tiles either. And the Pillage status NEVER changed on its own. So, is this a case of my game alone having developed a glitch? Or is this something Firaxis may have missed?
