Minecraft has stopped running because it encountered a problem; Exception in world tick

I could not find any existing issue that contains any of the crashes mentioned here. However, all of the crash reports that you have provided are from a modded version of Minecraft. Please try to reproduce the crash in a vanilla (non-modded) version of Minecraft and attach that report or this may be dismissed as being caused by a mod. You can view all information known about this specific crash at MCX-462.

This ticket is invalid as it relates to a modded or 3rd party client/server.

• Any non-standard client/server build needs to be taken up with the appropriate team, not Mojang.

• Any plugin issues need to be addressed to the plugin creator.

• This site is for addressing issues related to the base unmodded MineCraft.

Well I just deleted my entire .minecraft folder, removing all my mods and my magic launcher for no reason because it just gane me the error again.

I added the file

Well that's a totally different crash than the modded one:

Description: Exception in world tick

java.lang.NullPointerException
	at arj.b(SourceFile:210)
	at bdl.a(SourceFile:1145)
	at fd.a(SourceFile:99)
	at ci.b(SourceFile:350)
	at bdl.d(SourceFile:95)
	at bdt.b(SourceFile:58)

Is there something I can do to fix it?

Does the crash happen on a specific server or on any kind of server?

Any kind of multiplayer server
I can't seem to duplicate the problem in single player.

Is this still a concern in the current Minecraft version? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.
