Searched a bit and was surprised to find nothing about this. I know the chest used to be bugged and was fixed in one of the 15.xx patches but since 17.6 its been broken again. The fix made it have the same mods as chosen but with slightly different ACs, in 17.6 it was changed to give 10 bow instead of 30 and add 10% nanocost rather than subtract 5% (at QL300)
Seems they made the exact same mistake again or am I missing something here?
I know lots of people won't care due to ofab but T3 is still useful if you want to twink bow whilst not having access to good VPs.
