Frozen Caves break bedrock

If weirdness noise value is above around 1.5 & the temperature noise value is below -4.5*, frozen caves can break bedrock. This is basically identical to the issue with sulfur caves in their first snapshots.

An example seed for this is -7913918769942214574 (found my me), the weirdness value is very high, causing the frozen caves to go below bedrock.

*there’s probably more noise types at play here but im not very experienced with noise types outside of the 5 climate types, crunchiness & cave noise types

EDIT: It seems that frozen oceans also cause this bug to happen
