The only other things I can remember being worthy of mention in that Official Guide are the DR and DT values of armours against electrical attacks.
In the meantime, more bugs:
Toxic Caves:
# The floor by the southern wall, near the beginning of the cave, between the exit grid and the door to the southeast, looks like it could use some floor tiles.
Redding:
# In the underground map, in the room underneath the Malamute Saloon, the floor line by the southwest wall needs it's floor tiles.
# Also, the far eastern corner of the map, in the corridor leading to under Mayor Ascorti's house, is missing a floor tile.
# in the map under the mining companies/mole rat arena, in the room to the south that contains the two Wanamingos, the upper northwest corner needs a floor tile.
# In the same place, the easternmost corner could use a floortile...and the wall is also a little dodgy-looking here. More than usual, at least.
# Same map as above, in the room with the stairs that lead up to the boarded-up well, the eastern corner yearns for some cavern floor.
# And in the eastern-most corner of the passage that leads to the stair that comes up in the open grave, the floor once again is pining for a tile. Also, the southwest line of floor in the room with the aforementioned stairs.
# In the upper Wanamingo mine map, the very northwestern corner (right next to some stairs) lacks a floor tile.
# In the north section of this map there is a walled-off room full of barrels. In the room before that, which is also full of barrels, the northwest corner is a bit lacking in the floor department. It's right between the two stacks of barrels.
# North of the exit grid in the southeast corner of the map, the easternmost corner is...you guessed it, missing a floor tile.
# Southwest of the abovementioned exit grid is a ladder leading to the lower level. If you go up this ladder, you emerge about three tiles too far to the northeast of the ladder. Also, just to the west of this ladder, a pile of rocks is "sticking" out of the wall.
# On the lower Wanamingo mine map, the northwestern corner of the room with the stairs, which is north of the goo-filled room, a missing floor tile.
# If you kill all the molerats in the molerat arena, you can still place a bet with Jackpot Jane on a molerat fight. She'll go into "Fight commentator" mode, and stick there, because there are no rats around to fight.
Military Base:
# On the first floor, in the room with the elevator, the floor along the southernmost wall needs a couple of floor tiles.
# Close by, in the room with the two computer panels, a section of wall is missing along the southeastern wall.
# In the corridor going southwest between the entrance and the room containing the generator, the floor is missing floor tiles along the southeastern cave wall. Also, you can stand on the broken piece of wall in the top most line here.
# From the entrance, head northeast. The far eastern corner here is missing a floor tile.
# From the entrance crossroads, head northwest and then turn northeast. The right-hand wall here is lacking floor tiles all the way to the far corner.
# When heading towards Grundel, just before the path gets really narrow, there's an alcove to the southwest. The innermost floor is missing floortiles.
# At the end of the passage where Grundel is catching his food, the floor tiles are missing along the cavern wall to the south.
# Melkhior still blurts all of his speech out at once. He says "Stop!" which sticks around for a while, but then the rest just floods out of him.
Misc:
# I ran into a group of mobsters outside of New Reno, after I had become a made man of the Wrights, a Prizefighter, a Porn Star
and after having wiped out the other three families. For some reason, they had nothing to say to me. If I click on any one of them, they don't say anything, as if they're script is frozen or somesuch.
For the more observant of you out there, the missing floor tiles are almost all found in maps that use the "cave" tileset, and are always in areas that aren't outright visible. The only exception to this is New Reno, which I know is missing a few tiles here and there, but I have yet to finecomb for bugs. So there's still more to come.
