I'm using 21.5 part 2, and It's a fresh install just using the old saves. Somehow the old saves must be causing these crashes though since Selebus went and rewrote some of the dialogue in scenes..21.5 part 1 is outdated. Use .21 part 2, which doesn't need any restoration patch. The Compressed version seems to be mislabeled, from the problems people have been having with it.
I really wish the mods would just remove the links to .21.5 part 1 and the restoration patch from the front page, because they keep confusing people. .21 part 2 is newer than .21.5, and .21.5 is Legend of the Huggy Boy without sexual content.
Haruka's invite sex scene causes a crash, I can ignore my way through the fiinish of the scene at least.. but it does crash every time towards the end, and looking at Kaori's phone picture will cause a crash.
