So... Completed episode 4 saves will crash regardless of stats and paths. We have to start over from episode 4 or earlier saves than episode 4 (probably, haven't tested), No episode 5 starting point on path builder, Episode 5 scenes not added to scene gallery.
Without a shred of doubt and suspicion, we can call this update "Incomplete". Not to mention all the bugs, glitches and errors we have to navigate to complete episode 5. We can only try downloading again after a few weeks and then play CK.
It feels like it's too much to ask from the developer to publish the game after fixing most problems if not all the problems.
It gets worse I'm afraid.
After examining the files more thoroughly, we appear to be missing renders for entire scenes...
I redownloaded from another source just to check whether it was me, but it's not.
For example
From my findings and checking the images.rpy for the update ("ep5") the following are missing:
animations missing (anim folder missing):
ep4/scene 93d/animations
ep4/scene 122d/animations
whole scenes missing (renders):
ep4/scene 92
ep4/scene 124b
It appears they either didn't make them in time for 5.0.0, or QC missed it

Hopefully they fixed this in 5.1.0.
