Fixes v0.937.4

We got reports that the game got very difficult at some points. The issue was actually that few new bugs appeared as we are building systems that track everything that happens in battle for the new After Battle Stats feature. So several units throw bugs around shield abilities and those shields would stay on units indefinitely. As well as a few other minor issues. But now we tracked them down, and auto tested all units to make sure this is no longer happening.

Also there was an issue with the Mac version that is now fixed.

We apologize for the inconvenience.
