All possible bugs, glitches, imbalances, etc. that I find will be reported in this here thread. I've noticed that in trying to note a complete list of all CM items, that I can't search for them in the Keep on the Hinterlands and in Shops. If you search your item collection for "Artifacts", "Citadel" or "Acquisitions" [both in the test server and the main one], you get a full list of every item you have from the AOTA, ETTSC and AI expansions, respectively. This doesn't seem to be the case with "Castle Mitternacht" and CM items, though. Bug?
