Random crashes when downloading Forge playing MeatyPack

[skywalker3271]

Hello,

I'm playing the Meatypack modpack on the Curse launcher. after it opens the vanilla launcher, I experience random startup crashes after hitting play. It seems to hang up sometimes while downloading forge. I have spoken with the modpack creator and he recommended I submit it to you for review. Attached is the latest crash report from the launcher. Please advise:

This is very strange but this error persisted after a complete wipe & reinstall of the pack. Stranger still is that now, without a reinstall or update, it's no longer producing the error, even after several client restarts... I will continue to monitor & post if it occurs again.
