Thanks for your reply.
" jungle temples and possibly other structures are extremely hard to find in BTA as of 3.2.2. "
I agree with this. After searching in the seed for hours and hours in Creative mode， almost a 7000-block radius. I find 2 temples in the Mangal biome. wired!

I have Better-Terrain-Addon-3.2.2, Better-Biomes-Addon-3.2.2, with the seed 6713577189027001870, after-hours finding, searching for many jungles, but there's no temple there. Is there a buggie or something?
