The carver for the crevices and mega caves tends to override structures (mineshafts, dungeons) as well as biomes (like Trees), leaving unnatural looking shapes. A way to resolve this, or to exclude certain types of blocks from the carver would be appreciated.

Hello! Quark's moved to 1.18 now-- unfortunately, this means that (unless your bug is critical and/or game-breaking), we're closing support for issues filed for versions prior to it (e.g. Quark on 1.16).

If your issue still occurs on 1.18, or if your issue happens to be rather critical (e.g. consistently crashing the game with no other mods present), please leave another note or open a new issue. Thanks for your cooperation!
