Part builder not working

[InkedMommyMC]

I am playing with Tinkers via Cloud 9 mod pack. All of a sudden, the part builder stopped working but everything else is fine. I tried breaking it and putting back and also creating a new one but still nothing. I put in the materials and tool template and it gives me the stats but no output. Also, every now and then, drains will stop working and I have to exit the game and then go back in for it to work again.

Check your logs

I have since backed up all my FTB files onto my external hard drive and the deleted any related folders and files off my computer. I reinstalled FTB Launcher and Cloud 9 and now when I put that saved world back into the saves folder it gives errors that all the mods are missing.

What logs specifically should I look for?

Sounds like your modpack got issues. And the log probably was swarmed with exceptions. Anyway, there's nothing going on on my side here.

Yeah. The log has tons of errors. I guess I am gonna have to start over from scratch :( Thanks for getting back to me anyway!
