bug: hide/detect hid/scan or mob with missing desc

Within a forest choked with mist Thick mists extend all around you, dense and cold. Visibility here is almost nonexistent, and those passing through here are forced to move slowly lest they collide with the numerous trees that are all around. Even still, whipping branches provide a constant annoyance to your travel through these woods. Above you, the sky is impossible to see, and between the fog and presumably the canopy of higher branches, you cannot even tell whether it is day or night. The forest extends in all directions, equally choked with fog and mist. [Exits: north east south west] <100%hp 100%m 61%mv 2752tnl (34.48%)> scan all You scan north. You scan south. You scan east.
