Slitherine

Not sure if this just happened in the game I was in or if this will happen in every game but I was playing as the Allies and clicking on various German cities and the elite button was highlighted on most of the cities. When I pressed the elite button it asked me would I like to upgrade the unit.

Version 2.0 version 2.1?

We have done numerous changes between 2.0 and 2.1, including fixing glitches. So if your glitch is in v2.0 then it's probably already fixed in v2.1
