Only has happened to me 3-4 times the whole beta and haven't seen it but once in this current game.

After a save load, very rarely the cursor and the tiles seem to fall out of whack.  After it happens; To select a tile on the main map, or in tactical that you want to go to or make an action, you only get the bottom 1/3 of the tile in mind and the top 1/3 of the tile below it to click on.  If you try and click on the center of the tile you want to goto, you will end up going to the tile above it.  Just an annoyance really.  Nothing game breaking.

Reloading has always fixed it.

Another little one.  Mantle of Oceans was leaving an artifact (blue glowing ball of light with a blue ring around it) after every turn as my champ passed through the area.  Went away after a reload.  (0)........(0)..(0)......................(0).......... Reload.

Still enjoying this game.
