When you place a sponge were running water is flowing and it dries the source near it (expected), the sponge does the animation of drying like in the nether and then it dries up instantly (unexpected), if there are any other water sources near the sponge but out of its range the water starts to glitch (Kind of) it starts to flow touches the sponge and dries up the water then the sponge does the animation and everything repeats but, it starts to speed up and the water animation cant keep up so it looks like the water starts to glitch.
