I did a sector 9/threat level 6 push today. I had given Odin and Galan's pre-fights to Hercules in rooms 1 and 2, then swapped them out. Somewhere in the high teens, my game crashed (as happens all the time). When I loaded it back up, the pre-fights were gone. I didn't notice until zone 20, when the boss spawned with the node where they regen 1% per second if the attacker has no buffs. If I hadn't happened to have buff cornucopia on, I probably would've been road-blocked.
This left me with the choice of doing without Heimdall for 2 rooms, or powering through. Either way it was going to cost me hundreds of units, due to the lost willpower healing that Herc should've had with recoil masteries + Galan's pre-fight. I ended up powering through, but with slightly harder bosses I might easily have had to quit out in zone 20+. Even still, I'd estimate I spent 3-400 more units than I would've had to otherwise.
Has anyone else dealt with this?
(Attached image shows Herc with no crossed-swords pre-fight badge. Obviously doesn't prove that I had the pre-fights on to begin with, but I surely did).
