I hear ya. My autofarm team is running at about 99%, but that 1% chance of failure means there's a good chance it'll bomb out while I'm asleep. Not worth spending the Ironite on a mega refill overnight. Luckily I can autofarm it while at work, so I should have Magma Eddie in another 4 or so hours. I'll accept a handful of failures to finish it out in 300 runs instead of 600.
