🐶 Brief

If we close all windows of Proxyman, Proxyman doesn't revert the Proxy anymore. We have to fix it 👍

All done.

For anyone who are encountering this bug, please get the hot-fix at https://proxyman.s3.us-east-2.amazonaws.com/1610/Proxyman_1.6.1.dmg 👍

I also directly updated on the database, so if we update from old version, the fix is patched 🌮
