My experience with .61 so far with focus on bugs.
Overall the experience has been awesome, the responsiveness of the inventory, player animations, and fire fights in general has been awesome and makes the game that much more enjoyable for me. As far as naked players go, the best thing I can recommend for that atm is log out and in with your friends so you can see all of each others clothes and remain somewhat in sync with each other. That's worked well for us, with the reduced log in timer, relogs only take about 25 seconds as long as the server isnt full. Treat all naked players as armed and you should be fine. Relogging near dead naked players has consistently gotten their loot to show for myself and my friends. Super sonic snaps from weapons aren't working at the moment which isn't too big of a deal as long as you assume all unknown shots are at you. Overall very pleased with the progress the game has made, so the dev game has my thanks for making such an enjoyable game I keep coming back to.
