Judging by the post about 5.5 it might be a good idea to wait until the hotfix, that's what i'm gonna do.
Regarding waiting/not waiting for the hotfix, here is a quick guide!Yeah was planning on a fresh playthrough for the update, but think i'll hold off for the hotfix
If you are in just for Ginny & Grace smut (and the main story content), go for it!
If you also want to fully delve into the LORE, read every single piece of side content dialogue, and check all the side renders, then I would wait!
The hotfix will be out shortly (a day or two, if nothing major gets found)!
