Hey,
I've just taken some time to look into this and can confirm the following
1,2,3,4,7,10 - All of these are true.
5 & 6 - This is false; the cape will not work from the POH cape rack or when stored in the bank
8 - Just to clarify the above. The cape effect will work when worn, stored in the max/comp cape or on the Anachronia cape stand and it only needs to be in one of these to work.
9 - As far as I can tell, there are currently no bugs. If you are aware of any, please report them in game so our QA team can investigate.
If there are any other questions or concerns regarding this, feel free to ask (although it is the weekend so I will not be able to check the code until Monday!)
Cheers :)
