Slitherine

I have come across a bug of sorts where now no matter whether I play single or multiplayer I am unable to place any of the units at the beginning or for the duration of the game. When I click on the unit in my reserve tab and try to place it in a allowable hex it just higlights the hex but the unit is not placed. I have tried uninstalling and reinstalling the game, but it did not fix the problem. this only started happening this week, but it makes the game unplayable, because I cannot use my core forces.

I was able to figure it our, I changed the mouse buttons to 2 click and was trying to use the left mouse button to place units
