every time i attempt to use modpacks of any kind it crashes but every time with a different issue the first one i was told of was the foamfix part of modpacks i solve it then a different issue appears i am going to copy/paste the crash file report on to see if someone with more experience/knowledge can help as soon as possible sorry that it is long i just thought if seeing the entire thing is a better idea then a part only.
