Hacking taiHEN Offline Exploit Reboot?

[CatmanFan]

So I was able to install the taiHEN Offline mail exploit via SwitchKaKu, and I tested it out, and AFAIK it's more stable than the original HENkaku Offline exploit, except that when it's finished and automatically closes, the PS Vita reboots, and it tells me it has not shut down properly (it's still working though). After I close this prompt, I go back into Mail, and try the exploit again, and it's able to auto-close properly without rebooting. Is this normal or is it just a bug in the exploit?

Taihen is still unstable.

It happens here too or it just freezes and i have to manually shutdown the vita.
