Sculk sensors are not activated upon rain or snow filling partially filled cauldrons
The Bug:
Sculk sensors are not activated upon rain or snow filling partially filled cauldrons.
Steps to Reproduce:
- Build the setup as shown in the attachment below by running the following command and placing down some sculk sensors in the appropriate places. setup.png

/fill ~1 ~ ~1 ~15 ~ ~15 minecraft:water_cauldron[level=1]
- Set the weather to "rain" and wait for the cauldrons to increase their substance level.
- Take note as to whether or not sculk sensors are activated upon rain or snow filling partially filled cauldrons.
Observed Behavior:
Sculk sensors are not activated upon rain or snow filling partially filled cauldrons.
Expected Behavior:
Sculk sensors would be activated upon rain or snow filling partially filled cauldrons.

Can confirm
Is this still an issue in snapshot 21w05a or later?
This issue is semi-fixed in 21w05a. Sculk sensors will detect the vibration of the water filling up in a cauldron for the first time. The process of the water level changing from 1 to 2 or 2 to 3, is not detected by the sculk sensor, however. I've updated this ticket accordingly.
