Barrier blocks generate in bastion remnant

I can not re-create this issue, are you certain you didn't somehow accidentally place those barriers, I removed all the blackstone, polished blackstone etc, but couldn't find any barriers, then I tried looking for them with the /fill command, but couldn't find any.

Can confirm. Generated a world using the seed twice. The first attempt is was is shown in the video. The second attempt did not generate the same bastion remnant.

I'll try your seed, but mine hasn't had any, any i've tried three of them

But you were right, I'm not sure how you found this, being over 100,000 blocks from spawn

It does seem to be very rare though

Guess that makes sense. It seems it might just be a structure mistake. I did notice that bastions don't seem to be tied to the seed, as I generated the same world, using the same seed, and got a completely different bastion at the same coords givin in the ticket.

The rooms may be random, but that barrier is always there, which makes no sense, but how did a barrier get into that location, they aren't supposed to generate naturally

I found a barrier block in a bastion too.

It always happens in that place in that room, you can use these two commands and spectator mode to find them easier

/execute at @e run fill ~-15 ~-15 ~-15 ~15 ~15 ~15 minecraft:diamond_block replace barrier

/execute at @e run fill ~-15 ~-15 ~-15 ~15 ~15 ~15 minecraft:air replace lava

This will replace the barrier with a diamond block, and remove all of the lava around it

There's another barrier at the cords -10374 57 102245

I find the barrier.
