I have a Problem with Log. If someone attacks my Island, i cant press "Revenge" to pay back. Does someome now why? I did NOT press the button before.
Could it be possible you have already attempted a revenge on that player? You can only use the revenge button once per log book entry
Unfortunately then it may be the case that that fight record has been removed from the servers. This occasionally has to happen when we are running low on disc space and need to make more room. As there are a lot of players, and in turn a lot of fights and replays to be stored, sometimes we need to make more room. If there is no fight record there is no way to trigger a revenge and this could be why the button as disappeared.
