I’ve heard a couple other alliances experiencing this now, and it happened in my alliance yesterday.
When you click on a player from the alliance membership screen it shows that they are not a part of your alliance. No options are given to leadership of the alliance to promote/demote/or kick the member.
Three of us on at the time with co-leader or elder status saw the same thing. I saw it before and after I updated. several hours later another elder saw the message in alliance chat and was able to remove the member.
STaRoOo - If you see this, we accepted so we could talk to you about possibly being on a wait list for one of our other alliances! Put up a message in alliance recruitment and tag me with @Coppersky if you’re interested…
