Issue Description:

(Please provide screenshots if neccessary/possible. Images can be dragged & dropped into this window.)
Screenshots always fail to upload due to my playing region.
My rtg config is "enable caves=false" and "enable ravines=false",other density configs aren't touched.
Without h&c,caves are fewer(but can't be fully disabled;ravines can be disabled);With h&c and it's default config,the underground is a mess like vanilla,and cave&ravine generation behaves like rtg doesn't exist.

Steps to reproduce the issue: (If it's easily reproducible.)

1.Install newest rtg and h&c
2.Create a new world with rtg world type
3./gamemode 3 and dive down

Sorry, but I'm not understanding what the issue is here.
What do you mean by the underground is a mess like vanilla, and ravine generation behaves like rtg doesn't exist?

If you are using B:"Enable Caves"=false then caves should be completely disabled in RTG unless you have also set B:"Enable Cave Modifications"=false, in which case vanilla caves will generate regardless of the B:"Enable Caves" setting. To prevent any caves from being generated, you should use the combination of B:"Enable Cave Modifications"=true + B:"Enable Caves"=false. (Not very intuitive, to be honest.)

The same goes for ravines, B:"Enable Ravine Modifications" should be set to true if you want to change their generation. (Note: Ravines are disabled by default.)

If you are using any mods that alter cave or ravine generation (through Forge's InitMapGenEvent event), then RTG's settings will have no effect.

For the next release we are moving towards using generator settings in the Customize World Screen, (or the generator-settings string of the server.properties file for a dedicated server,) to control cave and ravine generation, and the config settings will be removed. Because of this, this issue has no relevance.

Sorry,but I really did "Enable Cave Modifications"=true" and "Enable Caves"=false" combination all the time when rtg and heatandclimate are installed.Also "Enable Ravine Modifications=true" and "Enable Ravines=false" default combination.
Just no screenshots no clues,right?Maybe heatandclimate alters cave or ravine generation (through Forge's InitMapGenEvent event) like what you say.However I'm not a programmer and I have no clue.

These two are my configs of caves and ravines.



These three shows the effect with only rtg and those two configs.




These four shows the effect with rtg and heatandclimate and those two configs.
I have finally realised that screenshots uploading never fails.Those pictures are just urls.

Please anyone here?It's my fault.
