Oddity happening!!! I had healed my armada, so only had a couple tokens. ~Got a private message about an armada within 2-3 hits from a kill shot. So, continued to "try" to kill them for the 2300 point reward, as my tokens replenished every 2.some odd mins.. Once I got them down to what should have been the kill shot (after 1/2 hour), I found them to be in a loop of maintaining 507,657,873 health, regardless of how many times I hit them. When it finally occurred to me to save up enough to hit them with 2 tokens, I found them dead. I'm playing via Armor Games.
Hmm, that's a puzzler for sure! I'll let the developers know, but can you also send in a ticket to Support with the name of the other Armada (if you happen to remember it)?
I got confused in process of trying to contact Support before coming here & writing what happened. But I"ll give it another go.
