Thanks for your comment and for bug report (I haven't discovered that)! Nice to finally have some feedback about the game from players.
Also good to hear you liked Osnowa. The more people will be using it, the more hope there is for its further development :) And please do write on GitHub or Gitter (https://gitter.im/Osnowa/community) if you have any problems with it. During 7DRL two developers (including me) were using it and I made some notes about bugfixes and improvements — going to apply them within next days, so stay tuned.
