Hello a question about minecraft Java?

I like to play minecraft Java survival and trade often with villigar and whenever I emeralds from Fletcher Trade so the trade with 32 sticks for 1 emerald after a while the guy no longer wants to trade and then there's an x someone knows why?

Same here. Play Minecraft sometimes, did research and apparently it should be because it somehow disintegrates. Not sure, but should be normal, don't worry.

You can't trade indefinitely with a villager. At some point he needs a break. You can trade again if he "knocks" on the thing from him, so it only takes a little while
