While there is no way to reproduce this well, this happened to me since bedrock has been out.
I have this problem and it is not exclusive to chests. Dispensers are effected as well and attempting to tap on where they are doesn't do anything. Since op hasn't added the format suggested, I have.
Steps to reproduce:
1. Find any desert or jungle temple
2. Check inside for containers such as chests or dispensers.
Observed results:
No chests or dispensers are in the temple. This makes jungle temples have no traps.
Expected results:
Dispensers should fire when triggered by the tripwire hooks, and lootchests should be there when they aren't.
I have this problem but I didn't think a had a double chest there to begin with. I will make a copy of the world and try to mess with it for a solution.
When you have the glitched hyphae you are unable to be dropped unless you do it from the inventory. I can also confirm this works on nintendo switch version 10.02
This has happened to me with endermen and horses, but the horses have to be dropped while jumping/falling in order to cause it.
This happens to me.
I can confirm, this happened to me and I am worried they all disappeared, which is very unfortunate as the ones that disappeared are the ones I spent a long time grinding on.
This is reproducible in version 1.16.40.
Can confirm in 1.17.0.
