This is a good one!! I went over on my 3* rainbow talismans today. Now got 108 so the game is complaining I can't do quests. No problem, I have a 4* talisman that needs evolving so I will evolve it to 5*. Actually no I won't as I keep getting the "Server Inventory error. Changes not saved. Please try again" error. So I have been trying - all frigging afternoon and keep getting this error. Tried at work, at home, different networks and still the game throws this error. So, I have 2 choices. Not play the game as it won't let me or sell the runes which I don't really want to do as I can use them. OK I should have kept an eye on things but at the same time we should be allowed to go over 99 runes without worrying if the game is going to be an arse about it.
