Since the most recent update the ranged units don’t seem to harm the enemy at all.
How on earth did I miss that!
Fixing right away
It was a “simple” typo, mixing up the casualty event name. I’ve done a new build that fixes this (170727.0708). It’s already up on Google Play and will be available on the App Store as soon as it’s gone through the approval process (1 - 2 days). If you have TestFlight you can already install this build version from there.
The iOS version (33) has now been approved and is available in the App Store.
