I checked the configuration of each biome, and they were correct as default (as you said)
But man... wtf?

So it is confirmed... there is a bug
(version TC 2.7.0 on 1.7.10 MC server (spigot) )

edit: see #280 for the original issue

Hmm, interesting. Temples are rare, I haven't found one yet, so I can't verify and fix this issue.

Are you using the default settings? If not, could you post or send your settings (email is on my github profile)? What is the seed of the world?

i am using the default Rare buildings settings of each biomeconfig and the general world config. I have customized the Biome lists though, so i include all of the biomes (and many changes at not border near and isle in biome) i am afraid this wont help, but i can assure you that i noticed a jungle temple building in a desert biome when i first installed and used terrain control for the first time (all default settings)

It's going to be difficult to reproduce the issue. I'll try, but no guarantees, it's probably a rare edge case.

it doesnt bother me, i am just reporting in
