Noticed this today when doing Roc strike with some new friends; I had a full load of rocket ammo, then realized I wanted to use my machine gun for the Super Good Advice bounty. I was depressed because I figured all the ammo would disappear when I switched, as usual. My 6 Rocket Launcher rounds transformed into 350 Machine Gun rounds!! No doubt as a side effect of 1.1.1, heavy ammo no longer disappears when switching heavy weapons (or so it seems, I haven't tested it beyond this morning's strikes; this seems like it needs rigorous verification). Also noted that the Ice Breaker does NOT go empty when you die and revive, but keeps a full 6 shots in the heat sink! This was a very good patch as far as I'm concerned.
