1.0.1: Pack not starting up

[_ratskin_]

FIXED
Known fix:
Force update, it's in options at the top (Big button says "force update")

Version:
1.0.1

What is the bug:
Platform: Mac
Operating system: OS X v10.10 Yosemite
Java version: Java 8

Summary:
I downloaded the Direwolf20 modpack and clicked launch, then all the buttons greyed out, (like they normally do) the launcher window disappeared (It was still in the dock though) and a new java app opened, called "Launch" (like it normally does) then the FTB launcher in the dock disappeared and the new app also disappeared, I believe it crashed.

It has been repeated 5 times (doing the same steps as I have mentioned above). I have deleted the pack and re-downloaded it, it still has the same problem. I have also tried Direwolf20 1.7.10 v1.0.0, the bug continues. I have tried direwolf20 1.6.4 pack and it works like it should.

Platform: Mac
Operating system: OS X v10.9.5 Mavericks

Summary:

Go to the options and make sure that "show console" and "reopen launcher after....minecraft" are ticked now if you crash use the pastebin button in the console to post a log.

Ah thanks, will do

@_ratskin_ please click the force update button in options before you launch minecraft again

@progwml6 I have looked in the FTB launcher under options and advanced options but can not find any thing that says "force update" or anything like it. Do you mean to look at the minecraft launcher?

In the FTB-Launcher there is the second tab "Options". Right on the top you have a long button titled : "Force Update ?". Just klick it.

 

[_ratskin_]

Stupid me, clicked it, it is force updating now. I will say when it is done

 

[_ratskin_]

YAY, it worked!
Thanks I will remember this next time I have a problem.

I would like to do more testing if the FTB people need it

Well, just try to get some achievements in SSP, CSP, SMP and CMP. Guess how many issues you will find by trying this "simple" task. And I don't mean the "achievement not obtainable"-problems but rather what happens to world around you while you are working on it. Some worlds completely crash and become corrupted, some achievments just don't work as intended, some crafting-recipes are somehow changed so thats impossible the craft them even with auto-crafting systems (wich you won't get the achievement at all) and so on.
It just simply starts with the avoidable exceptions on startup before you even load up a world ... goes over to some "kinda random but seems like intended" and finaly ends at random crashes without any logs at all.

So you should ask for "Do you need help by fixing it?" as WE (the players) are "testing" enough, or at least it seems like it.
