"Fallout" fever is currently ongoing, but that doesn't mean the fans aren't hyper-dedicated at spotting the pros and cons of the new "Fallout 4." The first major bug was discovered by the players recently, one that runs the danger of the total crash of the game.

According to a report from GameSpot, a poster on the Bethesda forums first spoke up about the recently discovered bug, saying that a settlement quest requires players to head to Mosignor Plaza. Unfortunately, those who attempt to go to the plaza will then encounter a bug that crashes "Fallout 4" back to the console or PC desktop.

The fans on the official forums are currently still waiting for a patch to mend the game-crashing bug, but Bethesda has yet to officially address the serious issue.

However, not all hidden surprises in "Fallout 4" are frustrating encounters. In fact, many Easter eggs are pretty cool that are placed there for the fans' enjoyment.

A separate report from GameSpot revealed one as the seemingly random numbers in a Flux Sensor in a Boston wasteland hut. Upon inspection of imgur user 1Times, it turned out that the particular numerical combination referred to the registration number of a star freighter in the horror film "Alien".

According to a report from Tech Times, more can be found as players delve deeper into the post-apocalyptic world of "Fallout 4." Among the cool hidden gems inside the game include the crazy monkey in "Toy Story," a "Jaws" reference and a cool alien crash site that rewards the player a powerful Alien Blaster weapon for discovering it.

Holotapes are also everywhere containing mini-games inspired by real-life favorites such as "Donkey Kong," "Missile Command," "Pitfall" and many more.

With so much adventure and a bunch of Easter eggs, the "Fallout 4" universe is so exciting to explore. Not everyone is in a rush to see everything the game offers, though. According to a report from VG247, a significant chunk of players is still holed up in the Vault.

Steam achievements reportedly reveal that 14.5 percent of all PC players are still inside Vault 111. The "War Never Changes" achievement is one that's rewarded as soon as the player steps out of the Vault post-tutorial. But while many have begun their journey outside, some are taking their time with the best-selling game.

"Fallout 4" for PlayStation 4, Xbox One and PC was shipped on Nov. 10 and is currently out in shelves.
