[MC-192229] 1.16 Sunken Ship Chest Crash

The back room on every sunken ship (i.e. the room with the door) has a chest which generates with a block of flowing water inside it. Attempting to break or open the chest without using a sponge crashes the game, whether on singleplayer or multiplayer.

This issue has nothing to do with the /locate function, only world generation.

Attached are log files of several times the server has crashed. The server is completely vanilla.

Can you provide the crash report

I updated the description and added a log files from times the server has crashed.

The TpS went under 2 so the game crashed automatically. This is not a bug. Allocate more RAM.

This issue had nothing to do with TPS or RAM allocation if you read into it, the only time either became an issue was the exact moment someone opened one of these bugged chests. The only reason I even bothered creating this ticket was because the last ticket I found that reported this issue was merged with a ticket concerning the /locate function, this should have been looked into and fixed already. Water is spawning on the same block chests are spawning, it IS a bug.

MC-190896 tracks this issue, it is related to the fact that the game struggles with the buried treasure placement and its corresponding map.

You can prevent the crashing by setting "max-tick-time" to -1, see MC-63590.

Not buying it, that issue was posted for 1.14, which I have never had issues on. This specific issue began on 1.16, on two separate worlds on both singleplayer and multiplayer. Besides, telling the server to not crash itself is a band-aid, not a fix.

Your server crashes because there is too much lag. The "watchdog" shuts down the server automatically if there is ever a delay of more than 60 seconds. The problem is that the generation of the buried treasure can sometimes cause immense lag, which can cause the watchdog to shut the server down. Does this make more sense now?

The crash depends on how far away the target of the map is. You might have been lucky until 1.16.
