You're welcome.
So if I understand you correctly, you are saying that:
1) Your account has been reset [i.e.: All your stats have been reset]
and
2) Whenever you type something, it displays messages you have previously typed before the crash
Regarding your first problem, you're not the only one. The devs made this post about it:
Lost Your Account
Start by going to
aurorafeint.com/verify. Enter your device id and click submit. If we recognize your device id, do the following:
Playing AF: The Beginning (do not own an AFII game)
- Click retrieve and do not click new
- If you cannot remeber your username, email me
Playing AF II: The Beginning
- You should be fine now that the server issues are fixed. Please start
the game go through the character flow.
Playing AF II: The Arena
- Make sure you have the most recent update
- You should be fine now that the server issues are fixed. Please start
the game go through the character flow.
If we don't recognize your device, please email me.
Your levels are incorrect
- If you are past the account setup and your levels look incorrect please email me
- If you are not past the account setup and are a new AFII: The Beg or AFII: The Arena player and still have AF: The Beg on your phone. Please close the AFII app you are using, return to AF: The Beg and use the "Sync With Remote" button on the profile page. When that button becomes unclickable you are synced and should return to the AFII: app.
See if that helps.
About your second problem, I personally don't have Arena, due to technical problems, but I haven't heard of old messages being typed yet.
I will alert the devs, but I'm pretty sure it has something to do with your cache/previous files.
