about a month ago a friend of mine on my realm said these white blocks were literally falling from the sky. recently I went on the realm and noticed these exact white entity blocks all over the place, scattered. I highly highly doubt they were once ant blocks seeing how there were so many and placed in random spots. plus my friend saw them fall. no idea how to get rid of them but it definitely ruined our world...... please fix mojang.  xbox

whenever I click a server it say's java.lang Nullpointer?

Still ocouring on beta 4

I was not aware of this!
I hope that this is implemented.

This has been an issue since the inception of smp.
In fact, this can, and indeed was on my server, exploited by a few players to obtain vast quantities of tnt.
They waited for the server to be clear of players, built a mob farming mechanism, and towered up to the sky limit in various locations around the map in order to artificially raise the mob cap.
This bug also has implications for new players joining a server, if player A is advanced and has explored most of the caves in his area, then player B joins and starts a base in newly generated terrain, then player B will experience abnormally high numbers of mobs, due to the higher number of spawn-able spaces in his area.
Furthermore, several major game events, namely finding the end and defeating the wither, depend upon being able to find sufficient quantities of certain mobs, so this issue opens up the possibility of exploits involving those mechanics too.
Another problem can arise when a player afk's at his/her xp farm, I have had players afk for an hour or more, building up monsters and practically shutting off mob spawning server wide.
There are also several more minor dependencies, slime for sticky pistons, string for bows etcetera.
If you ask me this is a major, but curiously ignored issue that affects a great many game mechanics.
Now, I am no java programmer, and I speak from ignorance when it comes to minecraft, but surely the implementation of mob caps on a per-player basis in smp can't be that difficult?

ya my inventory was full

This seems to behave differently depending on position in world, perhaps related to the order of redstone updates in a wire? like MC-11193?
I really want both of these fixed >.<

Yes it is. It has been for a long time. May also be related to MC-11449

I have this problem. Very easy to reproduce with serial encoders/decoders. It also seems to be somewhat affected by position within the world.
