Bucketing and unbucketing water may crash the server, same for water bottles.

[13:38:43] [Server thread/INFO]: [Player: Failed to parse item stack data: Value must be within range [1;99]: 0; Item must not be minecraft:air in shulkerboxes at line 244, pos 64]
[13:38:43] [Server thread/INFO]: [Player:         ( __replaceable(previous_item)]
[13:38:43] [Server thread/ERROR]: Encountered an unexpected exception
carpet.script.exception.InternalExpressionException: Failed to parse item stack data: Value must be within range [1;99]: 0; Item must not be minecraft:air

Since that still crashes the server, some variant of gnembon/fabric-carpet#2053 is still not fixed.

Has there been any update to this? i have had the same problem with bucketing and unbucketing water. its seams locational. i have tested it with glass bottles to water bottles and it crashes the server.
