1) There is no server sources anymore, EVERYTHING is on the 'Client' side of MCP as we merge everything together 2) Vanity shit like this si stupid and you wont receive any more help on it.

We do not convert Mods, that is the responsibility of the Mod author, if it JUST used ModLoader it would of worked fine. But no, he edits base classes. Go talk to the author.

well what is at line (World.java:1967)? Why is it saying its null? Protip: Your block ids are fucked up they cant be > 256 -.-

So either go to thaumcraft, or post a damn log? Mostly the first if you're saying its a thaumcraft bug.

Chunks... pretty straight forward if it was anything different it would of been stated.

1) Its one of the mods holding the reference to the world not forge/fml 2) I like how you randomly picked a line from the stack trace, and didn't even report the proper error... It seems that something you've installed, either a new base class or a new coremod screed up a method.

Use our download links not some random 3rd party website who just gathers links to generate ad revenue?

Run the launcher, not the appdata minecraft.jar

Typically this means that a mod you're using ins t respecting threads properly, judging by all the errors being thrown by flan's mod, i'd say remove that.

There are mods out there that are written for ModLoader specifically, these mods usually do not work when you put them on the server as ModLoader does not work on the server, and a modder has to take special care not to invoke any client specific code on the server. Seems that the mods you've mentioned have not taken that care and are not dedi server compatible.

Fixed

So after that rant I got that you want to assign properties to liquids, which in of itself is not a bad idea. We would just have to come up with a comprehensive standard list of properties.

You can already add potions and potion effects without an api. Using all vanilla features. There is no 'brewing recipe' its all done with bit manipulation and all items can have this string. Again, this is not needed, the ONLY thing that would be really needed is to expand the potion/potion effect arays, however, this isnt even needed as you can do it yourself if you need to.

1) That code is beeing deleted in 1.5 so, no 2) What error does this fix exactly?

Something corrupted your level.dat, in your world folder, delete it and rename level.dat_old to level.dat

Has nothing to do with optifine, the issue is bouncy castle, make sure you manually download and install it like any of the other dependencies, it should of done it for you but something seems to of gone wrong.

Quite interesting, nothing should be able to cause this esp not for forge as we don't directly do anything special with the rendering. I'd make sure to compleetly remove any mods you have installed and test it. If that still errors, i'd update your lwjgl libraries.

Ignore MagicLaunchers retarded 1 error its not actually a error. And use the universal download unless you know what the javadocs/src are, they are not for you.

Interesing the issue you may have runtinto was the timeout caused by your delay when clicking yes. Do so faster and you should be able to get on. I'll look into making something a little more.. user friendly for this situation.

1) uyjulian, stfu 2) You DO NOT need to install ModLoader EVER 3) FML comes with forge so you do not need to install it 4) Logs or gtfo.

Post your logs folder.

What part of DO NOT USE MCPATCHER don't you get?

Do not edit base classes, we do not support anyone who edits base classes. Even for something so retardedly trivial as this, which can be done completely without any base edits at all.

There would be a log in your logs folder, however, this is usually a issue with your computer just being really fucking slow. RetroGuard is not a Forge issue, thats basic MCP.

Ah another one of those hunger game servers or whatever. We've gotten reports of that happening specifically with that type of server due to something they do while starting the games, never been able to reproduce. I'd say go talk to them and figure out what they are dong to cause this. Resetting the player would do it, which they do have the ability to do.
