When I click on a tile directly nothing happens. However, if I left-click and then drag into the tile, information about the tile appears. I still can't move it to the hex grid. This is the web version by the way.
I have tried and tested on all of those browsers and works fine for me... Annoying!
You are using a mouse? As touch controls are not supported currently.
When you selected a tile and hover over the game board did you get an indicator (a coloured hex outline)?
I appreciate you both trying different browser's and trying to get it to work!
