There are several bugs which involve zoning or logging to resolve. (Take it easy, can't Regen or Heal, etc.)

It would be nice if the process that is invoked on my character when I cross a zone could be enacted upon a keypress.

Hit F12 for a Hard Save or something like that.

Does this exist in the game now?

I was teaming as a Doc recently and my char kept getting the bug where I couldn't regen nano. We were in the middle of a zone and so far from everything that zoning wasn't practical. So I had to log ever time. A quick save would have made my team and myself significantly happier.
