Hello, and I'm sorry for the frustration. I'm checking the save problem right now, and it looks like it's not happening on my older iPad. It must be a compatibility issue with the newer versions of the operating system that came afterward.
Unfortunately, as you may have seen if you checked the other threads, every single change from Apple means every single game developer needs to check code again, and there's no one updating the Fabled Lands code anymore. There are other problems such as being unable to store Shards in a cache. I am very sorry to say that your version may be stuck.
As to making Shards in the first place, well, that's a different sort of question! If you're okay with playing in these circumstances, then finding good quests and loot is a fundamental part of the game. Talk to everyone, learn what quests work for what characters, maybe try some gambling, maybe take up sea trade if you get enough money to afford a ship, and so on.
