* Sponges sometimes do not soak up water when placed and removed in certain ways, especially when water can flow in from above.June 19 IRC logs: "P5:43:30 <peerkoel> here's a glitch: build two sponges deep underwater next to each other, delete one, it all floods" [...] "P5:44:03 <Droqen> Water can fall into a sponged area if you remove a block from where it would fall into" [...] "P5:45:00 <wingboy> water just filled in around my sponge :P" [...] "P6:00:40 <liq3> OH I see. Make sure thehre's a level of water above both sponges and it'll flood the remaining one." (22:43 to 22:45 UTC)
