Yesterday (despite cleaning the bike recently), the muddy Norfolk roads did their worst - When I changed to a higher gear it didn't happen until further shifter movement, which then put me in an even higher gear than I wanted! Time for maintenance, and a clean of the cable guide on the underside of the bottom bracket, followed by a little silicone grease had it all working again. It made me wonder about making a 'shield' to fit over the guide and could be clamped in place between the BB and the cable guide, with an access hole for the allen key to hold everything in place and act as a drain hole for any water that enters. An issue would be the difficulty of inserting the cables, unless this is done before the cover is added, or a clip-on cover. Any creative 3D printer users on here?

You could try with a short section of cable outer.
