Your recent edits around Strathnaver have involved the deletion and replacement of a large number of features. Please could you try to follow the principle of 'keeping the history' (https://wiki.openstreetmap.org/wiki/Keep_the_history) in future edits? Keeping the history makes it easier for other editors to understand your edits and other past edits of features, and also means you won't end up inadvertently removing tags, such as the name of Allt Gruama Mòr as you did and were informed about in https://www.openstreetmap.org/changeset/173644213.

You have also deleted the waterway connections through lochs. This breaks hydrological analysis tools like WaterwayMap.org and I don't see what benefit there could be to deleting these connections. If you don't think they should be tagged as 'stream' and 'river', waterway=flowline is an option (https://wiki.openstreetmap.org/wiki/Tag:waterway%3Dflowline).
