Hello  Archon. Of course, it is normal. When we open the coalition chest, the program  generates different gifts each time. I got some such gifts in the past. It is why we have to have a clear
temporary General's inventory before we will claim our coalition chest, in case we will have some very important equipments stored there. In my opinion as a player, it is for the best to claim such coalition chests one by one and not use the option <open all> as we might be spammed with lower chests and might lose important equipment. Have an awesome game. 

so the purpose is to spam us.. is that right?

 lordtroi, It is to give the players who don't play Persian Position a chance to get more General items. Sparta isn't only us, there are a lot of players who would like to have them as they have a different way to play the game. I don't like to get them on server 1, but when I get them on server 3 it is a blessing. 🙂

blessing for receiving 50 pcs. of grade 1 coffer? 😂 

 Let me explain. I started to play on server 3, 3 months ago, I'm only 79 level and low in units and low in  Xerxes position. My team have a 100k minimum requirement to get the Conflict rewards. So, I use a lot of boosts to break general items, and those items from coffers,  have a long time of breaking. It is understandable if we judge the game according to our own gameplay, but Sparta is a game for all, not only for the strong🙂
