We got bug with slots, coz Royal Guadrs see Captain of rg 2x. Captain are in main clan, and when you give them captain of rg, it count them 2x. Also when i check /allyinfo its shows 95 ppl with academy. But we have 97 with academy.

We found solution for this but it shouldnt be like that. If someone have same problem plz 1 st full royal guard with 21 ppl and then select captain, it works.
