In the Eruption room in trial chambers, dripstone no longer generates under the fountain

The Bug:

 

Previously, within the Trial Chambers “Eruption” room, under the button-activated fountain Dripstone would generate.

 

This no longer seems to be the case, in current versions. The secret compartment still exists, but it generates without any dripstone.

 

Steps to reproduce:

1. Find a Trial Chamber with the "Eruption" fountain room
2. Make your way under the secret area of the fountain hinted at by the Copper Grates
3. Observe how it now seems to lack Dripstone, which was an intentional feature that generated every time, and a dev even wanted to show off once but noticed they were missing for some reason (was during a stream)
