[Experimental] No structure at location reported by “/locate temple”.

Last hour I wanted to find Witch Hut to try to make a Witch Farm.

At First,I used https://chunkbase.com/apps to do a location,but failed for several times without a break.So I gave up this way and tried another way ——to gamble it by “/locate temple”.

But I usually failed to find it and got nothing.

I noticed some phenomenons in findings：

Barely any signs for swamps,(Randomness)just some water blocks(sometimes with some lotus leaves)

Sometimes other ruins(villages etc.) or trees will neighbour the coordinates.
