I'm sorry that happened! It's not usual. If you have an older version of the game sometimes saves won't carry over when you update. but it is strange that adding the DLC caused the saves to disappear. I don't think it will happen again.
Just figured it out. Somehow my phone identifies my saves as junk files and deletes them whenever it cleans them out. 😭
Oh that's not good, thank you for letting me know. I'm not sure if we can fix that on our end but we'll look into it.
Thanks. You guys are the best! c':
