I am presuming that this is a bug.
Note the 'more' under Apparatuses in the screenshot below. When clicking on 'more', the wheel spins temporarily before vanishing and no further results are shown. The 'more' remains. I am guessing this behaviour is a result of the fact that there are no more Apparatuses to reveal.

This behaviour persists despite restarting L5 several times. However, on refreshing the passage guide, the unnecessary 'more' vanishes. A minor issue, I realise, but I am afflicted with a peculiar pedantry.

I have attempted, but failed, to generate meaningful logs. Let me know if you want me to try again.
This behaviour occurred while I was working on L5 (version 5.2a SR-1 (5.2.1.0081)) in Windows 7 on a PC.
