Preliminary note: I have searched for this problem, and found very numerous tickets on the subject.... however, I have found none of them OPEN for JAVA edition... all of them are "resolved" which means this is still a bug and not resolved (maybe even resurfaced?).

Since I can't reopen existing tickets, I am forced to open a new one.

I apologise if I should not have created a new ticked... but... I tried this...
Search terms "ruined portal loot"... all status except for "resolved" ... nothing came up except for MCPE-69003 and  MCPE-72432 which is not java of course  

The problem - NEW Map using seed: 414284818784059697

Picture attached.... ruined portal @ 80 ~ 48 – No loot  

I tried searching for other portals... even some 15000 blocks away - both positive and negative X and Z coords, just for kicks... and none of them had loot ? This is also a first, as I distinctly recall other 20w... snapshots that did have loot (to my knowledge, I didn't test all ruined portals, just occasionally with no missing loot issues).

Again, I apologise if I wasn't supposed to create this, but I could not find an open ticket for this problem on Java Edition.
