Steps to Reproduce:
Create a world with the seed
-2044586705
/tp 1661 26 -37
Observed Results:
No spawner generates.
Expected Results:
A spawner should generate.
Original Description:
I found 5 separate dungeons in my world, but none of them had an actual spawner inside - might be to do with the fact that they were all connected to a mineshaft - I also dug around them to see whether the actual spawner was somewhere else, but it seemed to have not generated at all - it is an old world though, so could be to do with new updates corrupting certain things/chunks - the picture shows one of the dungeons without a spawner. Not all of the spawners are missing in my world though; there were still cave spider spawners where they were meant to be.

Could you please provide the world seed and coordinates of the spawners?
The seed is 2044586705, and the coordinates of the spawner in the picture is in the top left π
Can reproduce in 1.16.201. The seed isΒ -2044586705
not 2044586705
- negative signs matter
Could you please provide some more examples of where this is happening, seeds and coordinates please.
