You sure DiEvAl? I found structures (incorrectly spawned) in one single biome. For example in the middle of the ocean surround by nothing but ocean.
Also, the bug is effecting all structures including villages... not just temples.
The problem is on every structure... witch hut, temple. villages, etc...
Posted one earlier on regarding a village and temple spawning the middle of a desert.
Desert village and temple in ocean biome.
Images uploaded in the other thread... with regards to seeds will try to find the one for the second screenshot. The first one was a custom map using world painter.
