yeah it is
i mean it should remove only the fluid
reproduce management:
1-placed oak stairs
2-right click it with water bucket
3-place a sponge near to it
Result: oak stairs gone with the water.

-Good catch with the sponges, I forgot those were in the game lol. That issue will be fixed next update.
-I didn't do fence gates back in Not Just Another Ruby Mod 2 because I was worried about mod incompatibility. Looking back, I don't think there would be any, so I'll add it next update.
-No tile entities can be fluidlogged because of how I implemented the mechanic (look at the source code to see more about this). Other mods can make their tile entities fluidloggable with some extra work, however I won't make vanilla ones fluidloggable, as doing so would require me to rewrite all of their classes, which would break tons of mods.

and also fence gates can't be waterlogged?...

and why it doesn't work for chests?

thanks a lot for the explanation.

the issue with the sponges has been fixed in v1.2, and default support for fence gates has also been added in v1.2

that's awesome!
