Currently, these are the errors I've found as if this moment (plus some other aspects):
=Broken Images
Ditto - First Encounter only
=Text related
Sunny - Male Sex gives no options
Demora - Female Sex as an Espeon has no conversation
Milly & Gwen - Male Sex has "Focus on the Pleasure Milly/Gwen Felt" option listed twice
Midna, Milly, Demora & David - Female Sex has "Focus on your own female pleasure" option listed twice
Window Shop - "Window Shop on your own" option is listed twice; if feminine is at max, only the option to window shop with Sylvia is listed
Ditto - Asking how their body feels while they are a male Umbreon isn't written out (as in nothing behind Sam asking the Ditto how their body feels is written); also "give male" option reads "give $Ditto 1 Male"
=Error Messages
Window Shop - Macro Error encountered
Cass - Female sex text contains an error stating "cannot find a closing tag for macro" six times; also contains one instance of an error stating "bad conditional expression in <<if>> clause: shy is not defined"
Zoey - Male sex gives out three different Bad Conditional Errors; specifically for Male, Male1, and Male 2
These are all the things I've found as of this moment, testing male Umbreon & Female Espeon; I'll see if I can find others another time.
