Hi,
Was having quite a good time with Elemental but I did crash after trying to retake a city I had myself taken from the enemy.
I was killing Carrodus who was trying to escape from tactical combat but succeeded in killing him 2 tiles from the edge of the map. This because I used a Mounted Hero (Norak on a Warg Mount). Here is the debug file. Problem might be linked to missing MountedWarg Animations ?
Hope this helps !
And BTW, thanks for the work, the game gets better and better. I will make another post with some suggestions
