This Prolly cause of being set to sandy

Hmmm, I thought it was checking for HOT + DRY + SANDY - unless it's not making into that bit of code for some reason. Do we know what Outback is registered as?

Apparently, it's HOT + DRY + SANDY: https://github.com/Glitchfiend/BiomesOPlenty/blob/0253add36a1fb9ceecea52cbaaeede67ae8cb72a/src/main/java/biomesoplenty/common/init/ModBiomes.java#L447

Hmmmm, maybe we should add another check for 'desert' in the biome name?

All sandy will get a temple it's normal

And if you get rid of sandy for desert other mods won't get a temple for example Sahara eb

Desert = sandy lol

Outback is supposed to be desert. That's what the reference real life biome is. The bug is that it's buried. There is an issue that that Outback doesn't look so much like a desert.

Ok, I'll close this as the biome's been registered with the 3 biome types that are required by RTG to spawn a desert temple. The bug with it being buried is apparently a hardcoded thing in Minecraft (Desert temples always spawn with their floor at y=64)

Also not being a bug :p
