I had a stack of two Horadric Lutefisk Cubes stacked and in my inventory and when I tried to put them inside one of them (together) it ended up crashing my game. When I reloaded, my game was not saved and I lost all of my progress of that session (about an hour). The autosave did not save aparently either. But after reading online about the giant fire blowing everything up, I'm sure I would have died anyway, so I'm not salty about my death or anything. If the game is still being updated, then this is definitely something to look into.
