Old World Blues bugs

Exploitable bugs

 * Even though this is only the third add-on, the level cap will change to 50.

General bugs

 * Similar to a bug in Honest Hearts, while playing through the main quest, the tick marks of undiscovered locations can disappear from the compass. However, it's still possible to discover them afterward.
 * In-game time may pass abnormally fast. For example, a few in-game days may pass for a whole year according to the calendar.
 * After completing Old World Blues, you may find yourself attacked on sight by the Brotherhood of Steel upon re-entering the bunker, or by the caretaker of the Brotherhood of Steel safe house, even though your standing with them is unchanged.
 * When talking to your brain after defeating Mobius, you get stuck in an infinite loop of a conversation concerning pleasant memories about Helios One and Jason Bright (Quite the ironic bug considering the conversation you just had with Mobius!).
 * When returning to the Mojave, you may not be able to talk to Victor or anyone on the Strip. This prevents you from using the Lucky 38 as a base. A way around it is to kill Victor and the rest of the Securitrons.
 * You may be unable to get caps for selling items to the Sink Central Intelligence Unit, and his stock will not replenish correctly. Make sure his cap total does not exceed 32,000 to prevent this.
 * When checking the DLC content on the main page, it may not show up but yet all content will be there when you begin playing.
 * With Old World Blues installed the amount of 5mm rounds found in containers and other sources of loot is reduced dramatically, to roughly 30% of what is normally found. This change only affects containers found in the Mojave Wasteland, and not those located in the Big MT.
 * Most members of the Brotherhood of Steel become notably weaker once Old World Blues is installed, reducing their Strength and Endurance stats by 3 and 2 points respectively, and removing Explosives as a tagged skill. This affects both unnamed members, particularly those found patrolling the area around Hidden Valley, as well as some named members including Linda Schuler, Knight Lorenzo, and even Nolan McNamara and Edgar Hardin.
 * Dead Money Perk Old World Gourmet is no longer working.
 * When entering Big MT, the enemy indicators ticks would appear much closer to the enemy, similarly to indoors. It is unknown if this bug can be fixed, as it won't go away, even after completing Old World Blues.

Item bugs

 * Even though you take all of the contents inside a storage container, it will not say that it is empty.

Miscellaneous bugs

 * If you bought all four add-ons, your max level still might be 40. On Xbox 360, you can get rid of it by going the Dashboard and reloading the game.
 * When returning to the Mojave, you may find your ratings with factions having diminished.
 * When loading an auto-save with Hardcore Mode turned on, your starvation and thirst meters will jump up over 200, despite those levels being low when the auto-save was created.
