Lost Ark's latest bug can be "game-breaking" and the only fix is to "fully restart"

gamesradar.com:

Lost Ark players have stumbled upon a "game-breaking bug" that prevents affected players from advancing in the game.

Although it appears to strike at random times, one particular player encountered it during a Valtan Raid, which "ruined the whole raid" as they were unable to resolve the issue without exiting the game.

The issue? Well, it looks as though since the May update, players are finding that their mouse pointer is "sticking" to menu items, making it difficult to see what's happening on screen, and impossible to do anything else.

Stating that a "GAME BREAKING VALTAN BUG ruined the whole raid by not being able to click !!!", Redditor Sagezu posted a video that showed the issue happening in the middle of the raid. It prompted several comments from other players who report having encountered a similar issue, albeit maybe not at such a crucial time as the OP.

Whilst some have found ways to temporarily solve the problem, it seems that the only way to prevent it from coming straight back is to quit the game completely.

"No, it comes right back unless you fully restart," confirmed another player. "At least that has been my experience. Changing characters removes the item from your cursor, but the instant you try to use one again, it happens again."

We'll keep you posted and hope that developer Smilegate is able to resolve the issue sooner rather than later.
