Missing-target NullReferenceExceptions in Unity DOTween occur when tweens are initialized on destroyed objects. Enforcing source-anchored design rules for SetLink, SetTarget grouping, and tween ownership prevents these runtime NREs by ensuring proper lifetime management.

To prevent tween leaks with DOTween SetLoops and lifecycle callbacks, follow explicit rules for correct callback expectations and tween ownership. Managing kill/lifetime code properly ensures tweens are destroyed instead of persisting silently in memory.

Yes, DOTween Safe Mode can mask real problems by allowing tweens to survive missing target errors silently. Applying correct Safe Mode semantics and source-anchored design rules ensures Safe Mode does not hide underlying initialization or lifecycle failures.

Correct async tween integration in Unity DOTween requires module generation for async APIs and using UniTask over legacy AsyncWait methods. Following version-appropriate guidance for UnityVersion async APIs prevents module mismatches and hidden failures during execution.

Incorrect DOTween Sequence timing is fixed by applying operational guardrails for Sequence composition. Reviewing explicit source-anchored rules for Append, Join, and Insert ensures tweens execute at the correct intervals without overlapping or missing animations.

DOTween initialization in Unity 2018+ requires following explicit rules for Init or AutoInit setup. Applying these source-anchored design guidelines before building DOMove, Sequence, or SetLink calls prevents hidden failures caused by improper initialization states.
