Hi all,
Version 1.16.2 will appear on the Play and App Store shortly, featuring a few fixes and enhancements:
Additional options of purchasing Unobtainium are now available: 1 and 10 units.
New "track" button appears on all enemy land tooltips, allowing to quickly add players to the tracking list.
Scenario with a group of markers (buildings, flags, resources) located too close to each other due to which only the uppermost marker is possible to select is now fixed: tapping on the topmost icon will send it further back bringing one of the other markers forward (thus allowing to cycle through the available markers in a stack).
As always, please let me know if you have any questions or feedback.
