This seems to be getting alot of people lately. but as far as i can tell its existed for some time
there is no way for me to catch and cancel the items being destroyed, it is simply not fixable
but if you die, and drop items, then a creeper, or a TNT goes off, or even if you die from one of the TNT's were using which blows up multiple times
you items can be destroyed by the explosions
any explosion that effects your dropped items apparently destroys them
be very careful peeps
