Another fix, hopefully it'll work as intended now 🙌

Fix:
-   More changes to the Encounter in SCP revisit, hopefully it'll be guaranteed -now- (thanks Starluft for testing!)
-   Era's End Entities Expert Achievement not firing due to The Slasher (Hallways Text Event) switch being missing from the previous corruption (thanks MadHatterBelial!)

Changes:
-   Increased pauses and how long text stays on screen for Blood Shadow Encounter for readability
