@Shtrumph, I also looked at your cities, and to add to what
@ed1960:
Fely FS has 8 inactives
Arendyll FS has 12 inactives, including the Archmage
Elcy has 4 inactives & 2 open spots - and I noticed that only about a dozen are doing the tournament on a regular basis, something I consider to be a marker of activity level
@Shtrumph That level of (in)activity will result in trading problems. I'm guessing you're asking about your Elcy FS (if I'm incorrect I apologize), and I also noticed in that FS that many of your members have extremely low goods production numbers compared to what I would expect based on their chapter level. Now Elvenstats doesn't take into account all the goods you get from non-factory sources, but it seems like your FS as a whole might be under producing goods. I was curious, so I pulled up a few random cities to take a look and, low and behold, several of your members, including some in leadership positions, have non-boosted factories. This means that instead of trading, they are trying to make most of their goods themselves. This is a fundamental misunderstanding how the game works, and makes a FS significantly weaker.
Honestly, I'd be packing my bags and looking for a new FS.
