Behaviour field without transient marker

A Behaviour instance field is not marked [Transient]. Behaviour objects are recreated on reload and cannot own authoritative state. The edit is rejected; the last good code keeps running.

#Common causes

• Gameplay values are stored in ordinary behaviour fields.
• A disposable presentation cache lacks [Transient].

#Fixes

• Convert persistent values to [Property] partial instance properties backed by the behaviour's ECS column, or move them into a component.

• For a cache that can be lost and rebuilt on reload, apply the Mark as [Transient] cache code fix.
