Summary
All devices in my island suddenly freeze mid-session while players remain fully functional (can move and talk).
The freeze lasts for random durations and causes all device logic and Verse scripts to stop working temporarily, which heavily impacts gameplay and ruins player experience.
This issue has been happening for about a month now and still persists.

Steps to Reproduce
There are no specific steps that cause this issue.
It happens completely at random.
Start a normal session in the island. Everything will work fine at first.
At any random moment during gameplay (sometimes after 1 minute, sometimes after 10 minutes), all devices suddenly freeze.
Players can still move, jump, and talk normally, but all triggers, class selectors, buttons, and Verse scripts stop responding.
After some time, the devices start working again, and all actions that happened during the freeze execute in order.
The issue does not require any particular interaction or condition. It happens spontaneously and without a consistent trigger.
Expected Result
Devices and Verse logic should continue running and responding in real time without interruption, regardless of how long the session lasts.
Observed Result
All device and Verse logic freezes for a random duration.
Players remain unaffected (movement and communication still work).
After the freeze ends, all pending actions trigger in order.
The issue breaks the flow of gameplay and causes players to lose interest and leave the island because nothing responds for several minutes.
Platform(s)
Affects all players in the session (PC, Console)

Additional Notes
The issue has been occurring for about a month and continues to persist.
It started appearing after a Fortnite / UEFN update around that time.
Occurs even with a small number of players in the session.
Freeze duration is completely random, sometimes 1 minute, sometimes 5 minutes or longer.
I have manually reviewed all my Verse scripts and confirmed there are no infinite loops, no heavy computations, and no logic that could cause a freeze or computation limit issue.
I even removed or simplified most of my scripts and devices just to test if the issue was from my island, but the freeze still occurs, suggesting it’s likely an engine or replication-related problem.
Strong suspicion it’s related to Replication or a Verse task blocking device updates.
This issue severely impacts gameplay, making the island nearly unplayable during the freeze and causing players to lose engagement and enjoyment.
