Admittedly I am not registered on the test server so I do not know everything that is being done on it.  That said, the inconvenience and headache caused by yet another sudden patch and its presumably unintentional impacts on things as unrelated as fleet tags.

Correct me if I'm wrong, but in my experience with many other games, the primary purpose of the test server is to make the transition from idea/balance concept to the live server as seamless as possible.  This suggestion isn't to downplay the efforts of anybody on the test team who have been putting in a lot of time on multiple different projects, but this suggestion is to stop the griefing of so many players on the live server by making changes to it without testing those changes on the test server.

The changes announced as introduced by last night's patch:

Patch V 1.368

1. The maximum ship capacity of an account will be increased:
-Normal ships: 40 ships
-Overall ships: 75 ships

2. The upper border penalty range for the battleship has been expanded.

3. /where command will not be working to HA participating player. 

Using the search function in the Test Server Discussion forum using search terms like 'capacity', 'ship', 'border', 'penalty' and 'where' yield nothing even relatively close to what we saw patched.  Someone who is an active part of the test server can correct me if I'm mistaken here and I'll close out the suggestion, but every part of this leads one to believe that these changes that were made last night were done without undergoing any testing on the test server.  The results that the live server deals with are bugged fleet logos and big backlash from the BB community.  Even the ship capacity part, which is a retry at a failed attempt to do the same change on the live server recently, doesn't show up anywhere in Test Server Discussion.

Overall recommendation summary is to apply and test every change that is slated to be applied to the live server on the test server first for adequate bug testing / test player feedback.
