Crash on world creation: mouseClicked event handler

[AngelOfCreation]

So, over the past few days I've experienced this crash multiple times in the process of developing my modpack. Upon opening the world creation menu, the game crashes. The description is always the same: mouseClicked event handler. It also seems to have something to do with VillagerTrades. I've included several crash reports from multiple iterations of my pack. Some of them list moonlight as a suspected mod, others don't.

Downgrade Forge to 47.3.25. This should be fixed by #191.
