You can preach RNG to me, but this is beyond that. Almost anyone that plays MP9-10 will tell you that 1-2 Legs a run is almost guaranteed and 4-5 is not unusual. You can't do 57 key runs and 15 uber MP10 runs and NOT get at least 1 leg drop. Its just mathematically impossible. There is a bug.
My question is, since I know this bug exists now for sure and I have the sample size to prove it, I'm sure others have seen it as well. Its probably similar to the fury generation bug that sometimes hits players. I've seen players go through that but then fix it due to reboots and unplugging modems and such. I've tried those tricks. Didn't help. I've tried logging out naked and then re-equipping. Nope. Tried a re-install of the game too. Nothing is working.
Have you seen this bug and what did you do to fix it on your end??
