I was checking my game output tab and found out that it was full messages of which item de ring of correction swapped to. I don't think this is a bug, but i wonder if you could change it so that unnecessary (at least for me) info won't be displayed (or maybe a config option). It is quite hard to find out why you game is lagging with this on your screen: http://pastebin.com/dpYG0bww 😜
