I bought lots of chromium packs and last when l opened last 32 packs i got the heroes and it shows my heroes stars get to 6 but when i close the reward window it stayed 5. It happened 3 or 4 times. It doesn't get higher than 5. It happened to jedi concolus, cad bane 2 times and qui-gon jinn. It might happened more these are the last purchases i checked and noticed it happen. I want it to be checked asap. I opened a ticket to support and they directed me here. So its already 30 hours . Sorry for my english.
