HOWEVER: I refuse to lay down and roll over for Mojang's disregard of the modding community. So....
HERE IT IS! I did put together a 1.4.5 Tech Pack for release. It contains a large number of tech mods and is only missing RP2 for the moment. This is a stop gap present and the real 1.4.6 present will be released as soon as all mods are updated.
AMCO Tech Pack 1.4.5
Because I want get this out for a Christmas release the current download is for a MultiMC install. However, by the time most of you know about this I will be able to get a Manual Install ready and uploaded. Same instructions as above for install. Tech Pack
The configs for the tech pack are different from those of the regular pack so you will need to start a new world for the tech stuff. A Manual Install will be up and ready within the hour.
And here is the link for the manual install: Manual Tech Pack
