Decided to create a 1.8.x modpack in Technic Launcher, got a server going but the client bombs immediately with the following:

Is this an issue with Forge 1.8 or something else?

 

Also is there a fix for this?

 

I saw in a previous thread someone got banned for posting an error just like this, I have two legit accounts for minecraft.

Darn, there goes Technic Launcher then including their new beta.

 

Do you know off hand which launchers out there setup the libraries correctly?

seems that neither the vanilla launcher nor forge b1245 downloads and installs the library "level":

 

org/apache/logging/log4j/Level

 

I'm at a complete loss here and from what I can see based diesieben07 response is that "we aren't supposed" to use launchers anymore, ie going back to the archaic way of doing things.

 

Gosh, I really hoping I'm taking that out of context. Please tell me that I am.

Technic Launcher needs to update how it handles libraries.

 

For now, I recommend using MultiMC.

Thank You, I'll be giving MultiMC a shot now.

Wow, MultiMC really did it right! Thanks again!
