The creators of Fallout 76 have hit a snag with the beta version as fans gear up for the full launch of the game in just two weeks.

A number of players trialling the pre-release edition of Fallout 76 on PC say that the 50GB game file automatically deleted itself when they launched the playable trial, Trusted Reviews reports.

Bethesda quickly acknowledged the problem, and admitted that some gamers would have to re-download the file.

But to compensate for the time lost, the US-based games giant is adding another four hours to tomorrow’s upcoming trial period, which will now run from 8pm Thursday to 1am Friday UK time, says Eurogamer.

Such trials, often referred to as the beta period, are used by developers to find any major glitches in a game before it goes on sale.

Before the first trial period for Fallout 76 kicked off on 23 October, Bethesda tweeted that fans might find “new spectacular issues none of us have encountered”.

With the next trial period getting under way tomorrow, there’s still time for fans to suggest improvements.

However, only players who have pre-ordered the game can access the trial, while everyone else will have to wait until the game hits store shelves on 14 November.
