I was responding to post #188 where the user seemed to think it was an intentional part of the update. My post was simply to explain what the intended purpose of the silver stars was.
You misunderstood me, for I don't think that at all. Obviously the purpose of these changes is not to create issues, but the issues are side effects from other changes. What I'm asking is, since these issues don't seem to be related to any of the changes in the announcement, what were those changes? What was their purpose, and why were they necessary in the first place?
If this had been an isolated incident I would not bother bringing it up, but this has happened over and over again. In every update there seem to be bugs appearing in random places that have nothing to do with the announced changes. Remember when you could both plunder and polivate the same neighbor in quick succession? That one was fixed very hastily, but there were not supposed to be any changes to the social bar in that update. Remember when quest pop-ups stopped working? Again no obvious change it could have been connected to, and took two weeks to fix. Remember when scouting provinces stopped working properly? That was ages ago, but it has never been properly fixed. There are no more JSON errors, but now when you enter the continent map with a completed scout, the graphics are pixelated and the map never focuses on the correct province. And so on, and so on.
My guess is that these problems are the result of tinkering with the code. I would bet that, if this game is anything like other web-based games, its program code is a mess of patches on top of patches on top of patches. I can imagine it being hideously ugly and hard to maintain, and the developers being tempted to completely rewrite parts of it. Maybe they have. But what they should do more is testing to make sure their changes don't cause worse problems than they solve. These should be the most basic rules in any development team. If it works, don't break it, and if you don't know what you're doing, leave well enough alone.
By the way, while those grey stars are used to mark buildings that can be upgraded, they are also used to mark buildings that can be polivated when visiting friends, neighbors and guild members. Also, since it has been possible to upgrade buildings since last year, whatever caused this issue is probably not related to building upgrades.
