Next gen version of my original mod: Here

List of quests that were fixed:

• Now or Never (first half of the quest in vanilla is set to level 11)

• King's Gambit (the whole quest was set to level 16 in vanilla)

• Pyres of Novigrad (first half of the quest in vanilla is set to levels 7 and 9)

• Echoes of the Past (the whole quest in vanilla is set to level 13)

• Novigrad Dreaming (the XP reward is set to level 10, so I changed only the suggested level that you see in the journal from level 7 to level 10)

• Blood Ties (in vanilla set to level 7)

Cause of the Bug:
These quests had different levels set for XP rewards from their suggested levels. So I only changed the levels in rewards.xml to match with their suggested levels and that was it.

Installation:
Simply put the mod folder in *your Witcher 3 directory/mods.*If this is your first mod, then just create a new folder called "mods" or "Mods" and put it in there. Mod Manager will probably work too. To uninstall, simply delete the mod.

Conflicts:
Use Script Merger to fix any potential conflicts.
