I tried to travel to the nether, and crashed. This issue however also occurs when traveling to other dimensions, and when switching from one save to another. This has occurred when loading my main save, then quitting, and loading a test world save. This crash also occurs when traveling to and from the twilight forest at times. The specific reason sited for the crash is:
"A fatal error has occurred during the network handshake, this connection is terminated. Check the log for details. The exception caught was: java.lang.NullPointerException: Cannot read field "field_147371_a" because "player.field_71135_a" is null".

there isn't the NullPointerException in the log that you provided, can you give the crashlog instead please ?

Here is the crash log

[Alexdoru]

thanks!

[Alexdoru]

do you have the config "machineWireFire" off ?

[Starcluster0]

Posted the wrong discord username, and I will check to see if so

[Starcluster0]

No, I have machineWireFire on, and I updated the discord username so you can message me on that.
B:machineWireFire=true

[Starcluster0]

To top that all off as well, I have every single wire covered by some kind of block.

[ClassixX]

I can confirm this, happens frequently when loading into my single player worlds. I'm not sure how wires might be related, but the world is in the stone age, so there are no wires.

As of 2.7.0 beta-4 this issue with a java.lang.NullPointerException has appeared to resolve itself. I cannot replicate this crash in beta-4.
