I think @Ruin Explorer has something like the right of things, here. The stakes are high and the situation is complex; whether either of those is "too" is probably arguable, but the party clearly want to be careful here, for reasons that make sense to them. I don't think having another group accomplish this while the party dithers is necessarily bad, but I think I'd want to try to figure out why the party is dithering--especially if they haven't been the dithering sorts before now. It's probably worth finding out their understanding of the situation and the stakes, and seeing if there's been a communication problem somewhere.
At least one of the parties I'm DMing has spent multiple sessions doing research on things, if they had reason to be think the stakes were high and/or the situation was complex. Everyone had fun, so I didn't mind going a session or three without combat, but if people aren't having fun at your table (and you are a person at your table) then it's certainly a problem for your table.
