There is a significant delay in resource synchronization within the base building interface. After unloading supplies from a vehicle into the main base HQ tent, opening the construction table/stand reveals that the new supply count does not update immediately.

Players have to wait over 10 seconds for the interface to refresh and reflect the actual available resources before they can begin constructing structures.

Steps to Reproduce:

1. Drive a supply truck to a base and unload supplies near/into the main HQ tent.

2. Immediately interact with the build table/stand inside the main tent to open the building menu.

3. Check the displayed available supply count in the UI.

4. Observe that the unloaded supplies are not immediately available for building, requiring a ~10+ second delay to update.

Expected Result: Unloading supplies should instantly sync with the base network, making resources immediately available in the building menu UI.

Actual Result: The building menu displays outdated supply figures, forcing players to wait over 10 seconds for the UI data to refresh.
