For some reason it only goes up to 1.9.0.4 so I put that

The problem in the op is happening in 14w32a

I am having the same problem but all the time. I think it cause the game cant keep up with 30-50 clocks that check at 20 times a second. I will upload the map as an attachment so you can test.

Its in 19a-26c

Yeah sorry I didnt see the date on it when i looked at it. It seems like the lag is cause by a summoning falling sand. Also this isnt an fps issue , its feels likes the server being out of sync

I just uploaded the map I had the problem on

Edit: I deleted all air blocks on the map I sent and there hasnt been a problem for a while , must be something to do with the blocks in the map i sent

Edit:2 Pasted the blocks back in seems fine , updated to 26b and it messed up

I having this issue. Its apearing in snapshots 19a and up(not tryed below 19a). Happneds after 10 - 60 mins of playing on it. Not sure if its the world or not .

Edit: Here is a forced crash report http://pastebin.com/tsGZx66B

Nice!

Works with any bit of water(13w07a)

If you look at the picture there is a fake scorsce block on top of the hopper where water was before i put the signs infront
