We're aware of an issue with Magic Trap not persisting on containers across server transitions.

To clarify, when you cast Magic Trap onto a container and then go into a dungeon or another town, the trap goes away but the container stays red like it's trapped & that is not intended.

We will work to improve this as time permits. The best known workaround currently is to trap or re-trap your containers when you arrive in a new area. Static Crystals do not exhibit the same behavior, so they may be a desired alternative to the Magic Trap spell until this issue is resolved.

We apologize for the inconvenience but thank you for your patience while we work to address your feedback.
