Underground: Lower Passages, secret passage does not show up

[Tomppa]

Area name: Underground: Lower Passage
Issue Location: See screenshot
Screen Shot:

Character says "Over here, check this out" as if I found a secret passage. There should be a secret passage here that connects to Arabel, Sewers. No clickable transition thingie appears, though.

There's also a high jump DC 20 that leads to a small rock where there's nothing.

Tested.
Fix confirmed for hidden passage and high jump destination.
