Is it normal to have 2 sentinel flares or did I find a dup bug?

[Panacea]

That.

[Mr. Bufferlow]

I have only ever had one. It sounds like a problem unless you intentional created another one or some how accidentally duped it. It would be funny if you could activate both and have two...somehow I doubt that would work.

[Panacea]

You doubt correctly.

There seems to be a bug in the progress flag for the quest to get that girl (boy).
Two of my five saved data have it.
I'm not sure if it's still there, bug.
According to my dim memory, when I was giving and receiving the corresponding items near the end of a quest, I suddenly realized that the completed items were in my inventory.
By the way, the two machines do not appear. They just switch on and off. (*_*)
