My game often crashes when trying to trade with my villagers and it will show this screen .It's so annoying and I have to open the app again. When  I loaded my world, the villager I was trading with has disappeared. This happens every time it crashes. Some of my important villagers like my master level armorer and cleric disappeared and they had such good trades. I don't know if this glitch is only happening to me or not. Let me know if you have a solution for this glitch.

How to get this bug

1. Get into the trading GUI

2. Occasionally if you do this the game crashes and the following or similar screen would appear (depends on what kind of phone you're using)

3. Reopen Minecraft and rejoin the world

4. The villager  you traded with should disappear

Expected results

game shouldn't crash and villager shouldn't disappear

Observed results

After opening the app again the villager I traded with had disappeared
