You might be right. When I get this message I usually assume they are being attacked already, I must admit I still don't fully understand the Arena slingshot bug!

@@ansonlam4081 Basic break down is you have three players, A at 1, B at 5, and C at 9. B attacks A, but during that attack and before B wins C attacks B. B and C each win. A drops to 5 for losing to B and since B lost to C, C moves up to 1 since that was B's new ranking and B drops to 9 which was C's ranking. In my opinion, B shouldn't be attackable since they would already be in combat with A, same as A couldn't be attacked by D (for example) since A's in combat with B. So in your video, with you at 9, you were in range to attack 5 but you likely lost a defense before you started your attack which is why 5 became out of range for you to attack. Since above rank 20 you can only attack up to four ranks higher it looks like two players behind you were trying to climb as well. Likely 16 was attacking 13 while 13 was attacking you and you were getting ready to attack 5. 16 beat 13, 13 beat you so you dropped to 16, 16 went to 13 and 13 went to 9 and 5 was blissfully unaware of the chaos below him since you were now out of range to attack them.

Thanks for your explanation, that's very insightful. I think timing also plays a part in slingshotting, but again not 100% sure how it works. I believe 13 would have had to complete the attack on me before 16 completed the attack on 9 in order for me to be slung out 7 places. As you say, 5 was probably oblivious to the bedlam happening below him!
