1.6.7 misc
Misc bugfixes, see commits.
Two balance changes: make Heighten Fear check if you have LOS of the target rather than if they have LOS of you, having antisynergy with both Darkness and the new Predator tree feels bad. Shadow Senses lets you use Stone and Merge on shadows you don't have LOS of, since that's already what it does to Shadow's Path and Cursed Bolt.
One QoL change, removing selffire from Corrupted Negation since no other Corruptor talent has it, and in practice it just forces you to tediously alt-target a couple extra spaces away rather than being a meaningful restriction.
