Village attack UI crash

Summary: During an attack on my village, I tried assigning more soldiers to fight. After two soldiers assigned, my UI crashed while the big, mean foe neared my town. Until I managed to restore it, the enemy almost killed half of my town.

Unfortunately I cannot provide copied error because I was trying not to get killed, and didn’t copy what the little text thingy said.

Notes: The UI seems to have crashed during game overload. Why do I say so? I have been building walls, which means all the scaffolding and the walls themselfes were standing. And it was night, which meant the game had to load all the light sources and fire pits.

Version Number and Mods in use: No mods, game version Alpha 21
