I am tired of OMF crashing at level 13, this has happened to me over 6 times already. I play OMF for however long it takes to get from level 7-13 and then suddenly when I am about to go into the last wave to get my items it crashes. I am tired of this happening, biggest waste of time ever. Its freaking frustrating because I played the level 3 times just to complete it and then it crashes when I'm about to beat it. Fix this ASAP.
