another "bug"(cuz it maybe not) : i was doing my best run ever, and then round 200showed up, and it was like the 2 Fortified BADs where invincible, so i tryed to beat them in sandbox mode, did EVRYTHING i could to beat them (even using glitches like no-cooldown, buff paragons(all degree 100), and even the permacharge bug), and even that didn't even changed the sprite, so i think you acidently(or not) made them imortals
