i grow tired of them not updating, why cant they just make it to 1.5.1
I feel really sorry for people like you.
It's not always easy to update, even if it seems to be easy for some modders. Every mod is different and every modders free time is different. If you want to use the mod so badly stay on 1.4.7 (or go back to it). Nobody made you use 1.5.x and it's certainly not up to the modders to work to yours, or even Mojang's, update schedule. If you use mods you either wait for them all to update or you move on without them. That's the price you pay for using them.
They have recently stated that they are working on it, seeing as Forge has (hopefully) stabilised now. That is something that was needed and was out of their control. It will appear in due time.
