For about the last 2 days, every time I try to join my friends Pixelmon 3.2.3 server, my Minecraft crashes... It says "Logging In", then I crash. But, I can join/play on a single player world just fine. I know its not the server because other people were able to join it. This is what comes up when I crash:

Thanks so much for your help!

Hi Jul,

I had the exact same problem and tried to find ways to fix it over several days. It's a problem with 'Underwaterfog'. You must have dived underneath the water on a pokemon, I did exactly the same. I managed to get it sorted using the method below. You'll have to pass this help onto your friend who's server it is, as it's to do with the server.

What to do:

- When you launch the server, a command prompt will come up and will list the players within the server. You will find along the same lines as 'UUID of player (yourname) is ba657aaa'. The UUID code is the thing we need. WRITE THIS DOWN, ITS VERY IMPORTANT. Close the prompt and follow the instructions below:

- You need to go into your minecraft server folder, which can be accessed in either your Documents, your Local Disk or your .minecraft folder (depends where your friend saved it)

- Once you have located the world folder, double click the 'players' folder

- Locate the .dat file in the players folder, with the same UUID code as yours from the command prompt

- Simply delete the .dat file connected to your profile. This will see you as a new player on the server.

Then you're done. Unfortunately, you will lose everything in your inventory at the time of signing out. However, there is a strong possibility that you will not lose your pokemon.

Hope this helps, if not, give me a shout and I'll help you out.

Regards,

Joe

Hello. I've got the same exact problem with the same crash report. Tried to follow Joe's way but I got lost. D:

I cant understand.. what am I actually supposed to do in the first step? The problem isnt about running a server but joining it. --Aint it?--

Hi Kyurishi,

The server host needs to follow the steps I listed above. There is nothing you can do, as it's a server issue. When you try to connect to the server, a command prompt should come up, saying the person has disconnected. Like this: http://gyazo.com/76d85ffd2d04d32e01bed9fb5d3f82a2

Regards,

Joe

Oh, I didnt read that line, jumped to the steps. Thank you again, but I guess that's not my case. :|

Hey, this is King, the owner of Jul's server. I want to thank you so much for helping us to get him back online! The server is grateful and forever in debt to you JSnevets..

Thank you again!

Yes... Thanks you so much for your help JSnevets!

I had the same problem and fixed it by modifying the Pixelmon mod itself. I editted the UnderWaterFog.class file so that the method throwing the exception simply returns. I'm not sure what effects that has on the mod, but it stopped the crash so that I could recall my Pokemon (it seemed to be out for some reason which may have accounted for the problem). Then I just restored the original mod and was fine.

Here is the modified class file: http://bumderland.com/minecraft/UnderWaterFog.class

You should make a back-up of your Pixelmon mod and store that back-up outside the Minecraft mods folder. Then open up the Pixelmon JAR file in your favorite ZIP editor (JAR files are just renamed ZIP files so I think even Windows can handle them natively if you rename them to .zip). Copy the class file to the com\pixelmonmod\pixelmon\client folder in the JAR. It will overwrite the existing UnderWaterFog.class file. Then start up Minecraft and you SHOULD be able to join the problematic multiplayer server. Recall all of your Pokemon or do whatever it is you think will fix the problem. Then quit Minecraft and restore the original Pixelmon JAR file.

I don't know for sure that this will help you, but it helped me. If this solution helps anyone out, let me know.

No problem guys,

Happy playing!

Joe

I have the same exact problem but mine is a little different.... I try to get in pixelmon servers but its Stuck on the logging in. Screen.... Does anyone know how to fix it? If so thx!
