People sure are getting worked up about this issue. It was not officially announced in-game as a problem needing to be fixed, nor officially announced as a bug on most of the forums. If someone from Beta had not brought the info to the other forums, we would have never known anything was being buggy/glitchy. So not having an official announcement at the time this was corrected, does not surprise me at all. And after all, if the folks who work on this stuff do not give the Mods on the forums the information, then there is nothing for them to share with us to begin with. As for compensation, the only players who may actually deserve anything are the ones who spent diamonds during these glitchy tournaments and Spire runs. For everyone else, it would be lucky if Inno even gave out some Supply and Time Instants to cover the cost of the lost troops and the time to make them. They don't care about any buildings used that players may have crafted or won from the Spire. That stuff is free, after all.
