I hate to say it, but I lost one this week too. Shot a doe broadside at 20 yards, thought it was a good hit.It was a passthrough, blood on the fletchings... One fletching tore off, probably hit bone on the way through. I climbed down after 15 minutes, checked the arrow, then packed up my stuff and packed it out to my car. Grabbed my lantern and started searching about an hour after the shot. I found no blood, but I followed the trail she took off on hoping to find her piled up. No luck. I probably ended up pushing her. It was a 1.5 hour drive, so I rushed instead of waiting for the next day, but I ended up going back anyhow. The only blood I found the next morning was a small splatter on a leaf about 50 yards from where I shot her. No other blood to be found. I looked for 5 hours, then it started raining heavy and I called it a loss. I'm pretty sick about it, but learned a lesson.
