Krasarang River Fixes

[orangefire]

The Krasarang River area was being phased for the quest "Unsafe Passage" but never removing that phasing once the quest was complete, which meant some creatures needed for later quests in the series weren't accessible anymore. I fixed it to properly end the Unsafe Passage phasing after the quest is complete.

REPLACE INTO `spell_area` (`spell`, `area`, `quest_start`, `quest_end`, `aura_spell`, `racemask`, `gender`, `autocast`, `quest_start_status`, `quest_end_status`) VALUES (65141, 6014, 30269, 30269, 0, 0, 2, 1, 74, 64);

Also fixed some IDs of Riverblade Pathstalkers that were not counting for the quest Blinding the Riverblades.

UPDATE creature_template SET KillCredit1 = 58858 WHERE entry IN (59098, 58985);
