Thank you for this report. Our developers are aware of this issue and they are currently working on it.

As soon as they prepare a fix, it will be released. Please be patient, it may take some time. Thank you for understanding.

This is also true when sending a Capture at a Relic Target.  Selecting troops travel time was just over 1 min, when sent it took almost 5 mins.  I have already submitted a support ticket, glad to see they are working on it.  Hopefully not like they are working on the bot situation though   yes I had to go there, once again.  As a long time veteran on many servers for this game it is upsetting to see things go down like this.  Until they find a way to take over my Haven though my ships will still be in the water daily.
