Shortly after the locusts when we enacted the rationing, Ingwald was recalled to Painford to handle the bookkeeping. Sieghard brought Rike with him to Ravenskird when he first went there and put her in charge when he left with it mentioned that he'd be returning to check in and help manage things as time allows.
After that, it got a lot less explicit. The plan was to enact the same rationing in Ravenskird, so it's reasonable to say that would involve sending him back and it's also reasonable to say that Ingwald could be doing a lot of back and forth keeping track of the numbers. If he's in Painford still, then he can look after it. If not, then another one of the veteran crossbowmen can keep things under control while Sieghard is away. Let's say Petar. Painford is fairly agreeable so I don't forsee there being an issue with that during Sieghard's hopefully brief absence.
