+// At the start of day 5, there is like always some dialogue with Grace.
+//
+// The dialogue script code about the drum book + veve newspaper clip is a bit broken.
+//
+// In case the player already has the veve, but is supposed to get the drum book, then the drum book
+// dialogue is repeated twice and the veve newspaper dialogue is also repeated (although it was played on day 4
+// in such case already).
+//
+// Drum book dialogue is called twice.
+// Once via GetTheVeve::changeState(0) and a second time via GetTheVeve::changeState(11).
+//
+// GetTheVeve::changeState(0) would also play the first line of the veve pattern newspaper and that's skipped,
+// when the player is supposed to get the drum book.
+// GetTheVeve::changeState(1) up to state 10 will do the dialogue about the veve newspaper.
+//
+// We fix this by removing the state 0 drum book code and instead will then skip up to state 11.
+//
+// More notes: The veve newspaper item is inventory 9. The drum book is inventory 14.
+// The flag for veve research is 36, the flag for drum research is 73.
+//
+// This bug of course also occurs, when using the original interpreter.
+//
+// Special thanks, credits and kudos to sluicebox on IRC, who did a ton of research on this and even found this game bug originally.

+// Applies to at least: English PC-CD, German PC-CD
+// Responsible method: getTheVeve::changeState(0) - script 212
