We recently found an game play mechanics issue where Polar bears will not spawn on grass blocks regardless of light level in specific biomes and instead will only spawn on a specific block type that can't be used. I know this lacks needed detail to properly investigate, and I would be more than glad to provide a full detailed description of the issue in a closed setting, but sharing this openly without knowing if there could be a possible solution, would compromise our base and give others a key advantage with regards to finding us and possible grief us. ClarinetPhoenix came to the area in question and confirmed our findings and suggested that we submit a bug report to see what could be done.
Perhaps you could forum PM details to the admin team? Maybe you’ve already done that, but its certainly a way to make sure your setup isn’t found.
This is actually an issue I ran into a few months back. On testing, it appeared to be an issue with core vanilla Minecraft itself. https://bugs.mojang.com/browse/MC-181691
Would have been nice to know somehow before hand (not saying its ECCs fault), RIP i guess. Also would be nice if the owner of the placed spawners could pick up their spawners and move them for these types of bugs.
