1. Kyral
2. eye of Horus west, Forest Realm
3. Windows 7 Ultimate
4. Heros Stars Missing after successfully upgrading to lvl 7
5. I was farming materials and decided to try upgrading stars for Cianna, Smoulder,Saffron and Shayd.
all were at 6 stars when i started. I successfully upgraded each of them to 7 stars. When i finished collecting the materials it was time to prepare for ragnarok
so i went back to town to set formation, heros runes etc. then i noticed that all of the above heros stars was at level 4 not lvl 7 that i used several hundred gems worth to get there.
so please fix this as it is a terrible system you have going and i feel completely ripped off. either that of fully refund all my money i have wasted on this glitchy game.

I had actually started to redo the stars again and then realized how stupid that was to spend even more money, So some of them are at 4-6 stars now.
