Hi, we do not intend to do anything to change or "fix" level 440 of Gauntlet Season 2 at this stage.
In each season of Gauntlet, there will be different puzzles and configurations to make progress through the levels, but there will also likely be a natural point where players hit a wall in terms of their ability to do enough damage in time (for example). It seems this season folks are hitting that at 440, and got there a bit quicker than expected.
There is no expectation that you must get through a specific number of levels to "complete" Gauntlet mode for a season, and there is plenty of currency available before 440 to pick up anything you might want from the Research Lab.
