With this update you need to be PL 88 instead of PL 82 to start the ssd 6 in Twine Peaks.PATCH 5.1
Just a tip. With v5.1 and Canny Valley story act 1 you can skip right away through to the next ssd if you have the right lvl.
I think you need to complete canny story or need to be in twine that you can skip missions between ssds.
I was in twine missions and could do throught v5.1 skip all lvl88/94/100 missions and do ssd 4, 5, 6 and could even do the next. My lvl was 96 but a friend who is 83 can do ssd 6 to.NOT
a solution like I said, just a tip
to skip missions if you are high enough.
Note: Maybe this be patched in the near future so be aware of that.
Happy hunting ^^
