Hello,

There is no tweak class for alpha versions after a1.0.5_01.

Why this should be added ?

By adding the alpha tweak class for theses versions, there will be no longer the username parsing problem, where your username transforms into PlayerXXX (Where XXX is a 3-digits number)

You should note that this will improve the backward compatibility.

How to add it ?

It will be very easy to add the tweak class on alpha versions.

The following line should be added at the end of the minecraftArguments string of each versions.

--tweakClass net.minecraft.launchwrapper.AlphaVanillaTweaker

Have a nice day !
