I see this was already fixed in a recent commit but please publish a new version asap as the current version is practically unusable with the chat spam (Calculated cheapest object).

Ho sorry, my bad. Yeah it must have spammed the hell out of your chat in the current state ! Thank you for opening this issue really quickly, thanks to you there is only 24 people affected. I hot fixed it in 1.7.6 and hopefully next version is going to be a lot faster. (I removed most useless calculation, but I need to figure out how to update when the scrap or peddler list of junk is modified before releasing).
