Game Crash Due to Commands

Hello o/

           My name is Anthony Schmidt and I've enjoyed playing minecraft since I was young and I love watching the game grow. The issue I've found relates to the latest snapshot (18w44a) with the trading then using commands. I've found that when trading with villagers (cartographers and librarians in my experiences) upon completing a trade then using /give to obtain an emerald or multiple, the game begins to pause certain functions. I was no longer able to select any villager to trade with, I was not able to open chests, crafting benches, furnaces, anvils, enchantment tables or redstone operations. But I was able to open/close doors, trap doors, and fence gates. I am unsure if that helps with anything or just causes more confusion. This 'bug' I guess isn't very  game ruining or a mass problem at the moment.

NEW UPDATE FOUND---Trading with cartographer causes the problems shown above, along with the other cause.

Thanks for reading this and possibly this problem helped unveil others one which will be fixed in the future.

I look forward to hearing back,

A. Schmidt 🙂
