This is kind-of a rant but also a suggestion. So I spent about 10 hours mining to get resources to sell. When my cave finally ran out of resources I had about 2 stacks of iron blocks, 50 blocks of coal, 14 blocks of gold, 2 blocks of diamond, a stack and a half of iron ingots, about a 30 gold, 3 diamonds and an emerald. When I finally went to sell everything I had a about 7 and a half hours of time left. I decided to sell the iron ingots first, after I "sold" them I took out a calculator to try and figure out exactly how many iron blocks I had. Before I could sell them I was death banned and lost everything. After being very confused for a full minute I scrolled up in chat. I saw that I had left clicked instead of right clicking and bought 64 iron ingots for 7 hours and 28 minutes instead of selling them. I basically just wasted 10 hours of playing, over a day worth of time in resources, all my gear and food because of me left clicking instead of right clicking. I have done the before with cobblestone but it was not that big of a deal. I think it would be better if there were 2 villagers, one for buying and one for selling so this can't happen.
