Gantt Chart - Card Dragging buggy

Hi ​@BellRed,

It sounds like you're caught in a frustrating tug-of-war with your Gantt chart! This snap-back behavior usually happens when there is a conflict between your manual movement and the automated logic Lucid applies to Timeline objects. To make sure I’m on the right track, it sounds like you are placing a Card onto a Gantt or Timeline template, but Lucid is rejecting the new placement and forcing the card back to its original assigned date coordinates. The blue box you mentioned sounds like the landing zone where Lucid thinks the card should snap on the calendar grid. When it works at random, it's likely because the card finally aligned perfectly with the Timeline's internal date logic.

To help me narrow down if this is a settings issue or a genuine bug, I have a few clarifying questions. First, are these cards synced to an external data source like Jira, Asana, or an imported spreadsheet? If they are, the Timeline might be snapping the card back because the Start Date in your external data hasn't changed, causing the sync to override your manual drag. Second, are you dragging the card into a specific lane or group? Sometimes if a Timeline is grouped, moving a card to a different row causes a snap-back if that row isn't configured to accept new elements.

In the meantime, you might find success by holding the card over the new spot for a split second until the blue landing zone box appears clearly before letting go. You should also check if the Timeline is grouped by right-clicking it; if it is, try ungrouping to see if the movement becomes more fluid. Another potential fix is to go to the View menu, select Grid, and turn off "Snap to Grid," as the document grid and the Timeline grid can sometimes fight each other and cause the card to jump back.
