Spelunky Co-op bug XBLA

[SuperSonicDelux]

I bought Spelunky a few months back, and I'm now getting up to a point where I can almost make It to hell. But I found a bug that has ruined many of my runs when playing on Co-op. After you get the hedjet, If your Co-op partner dies; then you save him, the bug occurs. Upon freeing your partner all your Items disappear. All your ropes, bombs, hedjet, gloves, etc. It's most common when you save your partner with the shotgun. I even have had a shop keeper open the coffin, releasing my partner and results in me loosing every Item, not not getting to continue my play-through. It has really ended a lot of runs for me. It's even happened inside the city of gold where I dropped my shotgun onto the coffin, releasing my partner, making me loose 50+ bombs 20 ropes, and many others.
