Funcom likes to leave unused assets in the dev kit, whether it’s to let us play with, or just something that they hadn’t finalized yet for x,y,z (the special arrows were in the dev kit for a good month or two before they officially came out). There’s lots of unused stuff in there, even old mount assets from way back when (wwwaaay back when, talking like 2017 stuff). So it’s 0 surprise that they left Crossbows chill there for us modders to play with, in whatever state they were in before they were left alone.
