A strange circle appeared around Hugul, and the game started to lag significantly; here's a screenshot: http://i86.fastpic.ru/big/2016/1230/4b/dba0c5159843efacc3636ca1a4b7a24b.png. Here's the save file (the game was running in multiplayer): http://rgho.st/7SjkNzR8K. It might be an individual problem related to the graphics settings, as I'm currently playing on an old laptop.
