I'm guessing you're spot on, Lex. Even the trace which did not come loose measures almost the same resistance to ground, and I think this is what was confusing. Not only that, but the resistance reads the same both before and after I glued it. I think quite simply, I need to add resistance to the ends to make 50 ohms.
