Raid victory bug

Perseus was in mount olympus and raided  nearby island. I won the raid but perseus remained at olympus and a new target appeared at the island I raided instead 

Hey Macamus,

This is because the reroll time can randomly be set too low, so that a player is immediately rerolled onto your island after you take it. We’re going to fix this in the next game update.

Thanks for the info!

Yesterday I had Perseus staying on an gold-island and fighting a beneath ambrosia-island. Even if I won the fight with 100% my hero was sent back to mount olymp (not the the island he was before). Ive seen this only once since Im playing OR.
