Heya again!
Sorry, I should have included this from the get-go.
The character is a half-elf, the bow is 'a delicate weirwood shortbow', of the variety that can be obtained from the Seldarine temple in Silverymoon (from the mob at Solonor Thelandira's shrine, Ranger Fara Pilininge), and the arrows are 'an arrow with a deep red feather' and obtained from the Tangled Trees fletcher mob (named something like Eyrlyn).
The mobs are the archery dummies at the range in Tangled Trees. During the day I have no trouble hitting them but as soon as night falls, despite their being visible with a look command, the game is telling me they're not available as targets.
I can't remember the specific message from that instance but I just tried another test in Silverymoon by shooting at 'a black bat' in the sewers. The mob is visible from where I'm standing but I'm getting the message 'You cannot find your target.'
Thanks again
