The platform is becoming unstable on my tablet. I use an iPad Air so it is slightly older and this may be a contributing factor. Even with E&P as the only app open it crashes on me regularly (3-4 times per day). Usually if there is a large cascade in a raid the app shuts down but sometimes it happens while in the basic basecamp view.
I have been able revenge the same player twice, winning both raids.
I won a raid battle quickly, the next screen showed that I had lost based on time (Time’sUp), no loot and lost cups. I immediately searched my tower and it showed me as the winner of the fight.
