Incase anyone else is experiencing this problem i found the answer to my 9th question.

9: If we contagion then smn bahamut, contagion magically disappears. When SB first came out I could have sworn it didn't used to do that. Did SE patch that to screw with us even more or am I imagining things?


I have it set so I do not see other party members debuffs. Tonight we cleared OS3 and my party noticed this. I would contagion and then smn bahamut but on my screen it would look like contagion would disappear. On their screens however it was still on the boss. So I am guessing when Garuda is replaced with bahamut, the game considers her buff a party member buff. So it looks like contagion wore off but it is actually still there.
