we updated the game today 20.05.2020, and here are the changes:
Units were not unlocked correctly. For example, the training of Elven Anti-Dwarf unit Whisperer should not have been available yet.
You will find the unlocking levels for different units here: FAQ
We fixed the unlocking levels for most units, and all training queues with Whisperers were automatically canceled at 17:00 CEST, and resources refunded. We did not remove the already trained Whisperers.
In addition, attack movements have been disabled from towers and portals under construction. In practice, this means players will not be able to create temporary gathering points as part of their attack strategy anymore.
Thank you for your understanding,
Your Arkheim Team
