Hello, I'd like to apologize if this was asked before but I tried a forum and web search for this but didn't find anything. When looking through model rail detail parts on the marketplace I see that in most cases multiple pieces are sprued together. However, number of separate parts seems to have no effect on FUD pricing, so are these sprues really necessary? Is there any issue with loose parts that I'm not seeing? The only thing I can think of is meeting the minimum part size requirements or protecting details that might break off, but most models I'm looking at shouldn't have that issue.
