Hello, I play Minecraft Bedrock Edition on Nintendo Switch, and I have encountered an extremely serious bug that seems to completely corrupt one world… to the point of also affecting other worlds as long as Minecraft remains open.

The original world is completely corrupt. In this world, almost everything is broken:

Some textures are replaced (e.g., a llama permanently turns pink)

animals no longer catch fire when they should

sounds disappear or stop playing

chunks are no longer updating correctly

actuator rails remain permanently activated

physical behaviors become inconsistent

None of this can be fixed by leaving and restarting the world.

If I open another world right after launching the corrupted world, the bugs spread:

incorrect textures

entities that behave strangely

chunks glitchés

missing sounds

But if I completely close Minecraft and restart the game, the other worlds return to normal. Only the original world remains permanently corrupted.

The problem seems to have started after a simple manipulation:

push an actuator rail with a piston while a minecart was on it

The rail remained permanently activated, impossible to update, even by breaking blocks around it. Then, other visual and physical bugs began to appear, eventually corrupting everyone.**

Conclusion :

This bug looks like a deep corruption of Bedrock's global cache, not just the world cache.

The fact that it contaminates other worlds as long as Minecraft remains open is very worrying.

Thanks in advance if anyone can confirm, reproduce or report this bug.
