Are unobtainable knowledges considered bug? There is list of all knowledges that are considered unobtainable by bdo community. Maybe it's possible to obtain some of them, but we didn't found out how yet. I would love to get confirmation that It's possible to obtain all of them and if it's not, then I think It is a bug and should be fixed. Some of them are from one time events that happened 3 years ago. These also should be added to game in some way. Example "Chief Manager Fughar on How to Live Life, Day x" - you could get those as quest reward from fughar. All 41 of those could be simply added as chat option to npc Fughar, 10 energy each. Simple solution that makes sense and fixes 20% of list. The link below is to google doc with all mentioned knowledges.

Please consider fixing it, because there are alot of players like me that like to do stuff on 100% and It just bothers and demotivates me that its not even possible to achieve 100%.
