A note on stability: This mod should not affect the stability of your game. It was tested extensively on multiple PCs running a base Skyrim install with the latest patch without encountering a single crash. If you are experiencing crashes, it is most likely being caused by your system and mod load order.

I keep getting a bug which was supposed to have been fixed in the latest version. Help!
Sometimes save games carry bugs from previous mod versions with them. To overcome this, after you update the mod, load an old save game from before the mod was loaded.

I'm not getting approached by the courier! Help!
Try entering and leaving a shop, as it should prompt the courier to arrive.
A workaround is to open your console in game with ~ and type "coc 000forgottencity01". You'll be transported to just inside the beginning of the game. If that doesn't work, the mod hasn't been correctly installed. If this happens, go to the Skyrim splash screen and click "Data Files" and ensure that "ForgottenCity.esp" is checked, and click OK. If it's not there, the mod hasn't downloaded yet.

This mod's music keeps playing after I leave the city:
Passing through the entry hallway (entering or leaving) should stop all Forgotten City music from playing. If all else fails, simply remove the mod from your load order; you don't really need to keep it loaded once you've finished the story.

Getting a permanent radiation effect on you
In version 1.4.0 onwards, entering the main city area will automatically remove the radiation effect. If you're getting a residual issue, passing through the entry hall will remove the effect.

Player gets stuck in the portal
Waiting for a couple of minutes usually sorts it out.
This is a rare bug and appears to occur on older PCs running a lot of mods. If after a few minutes it hasn’t worked, you can type “coc 000forgottencity02” to teleport to the correct cell, albeit in a strange spot.
Alternatively, you may wish to consider starting a new character, or loading a save game from a lower-level character (which usually has less "save-bloat"). This is reported to fix the portal bug.

Quest to defend the city from bandits / looters gets stuck
In Version 1.4.0 onwards, if more bandits fail to appear, enter the main city area. This should prompt the bandits to arrive.

Screen goes black under water
Open the console and type “teofis” or “ts”. Remember to do it again after leaving the water, or the lighting will look a bit odd.

Cassia dialogue freezing at end
Other players have reported that leaving the ruins, going to Skyrim, then returning and talking to Cassia again fixes this problem.

Gauntlets and boots are multi-coloured.
This only occurs when your texture settings are set to "Low" or "Medium". I suggest increasing your texture settings. If your PC won't run this, please use this as an excuse to go out and buy a new PC. ;-)

A key NPC dies unexpectedly in conversation.
This is fixed in version 1.4.0 onwards.

I keep dying when falling from the Citadel balcony.
This is fixed in version 1.4.0 onwards. If for some reason you're still dying, simply turn on Immortal mode temporarily with console command "tim".

When I try to open the Lakehouse door I heard a voice saying "My letter..."
You can only open the door once you have the letter on the table. If forme reason that doesn't work, open your console with ~ and type "setstage 000fcquest02 100"

I want to go back and play this again, but I forgot to save before I went in.
Save your game outside the city. Quit. Disable the mod. Start the game and reload your last save. Save again. Quit. Enable the mod. Start the game and reload your last save. You're done.
