Critical!!! Gameplay Systems Broken After v41.00 Update – Published Island Unplayable

[JustRONII]

Summary

Since the v41.00 update, multiple critical gameplay systems on my published island have stopped working correctly.

Issues observed:

Playtime tracking only works for some players. Players can be in the same session at the same time, but only some of them receive playtime progression while others remain at 0.
Eliminations are inconsistent. In some sessions players cannot eliminate each other at all, while in other sessions it works.
Leaderboards are not updating correctly because player statistics are not being tracked properly.
Players are able to edit builds that do not belong to them.
Sprint while flying is not functioning correctly.

Important information:

The island was working correctly before the v41.00 update.
Multiple updates have already been published in an attempt to fix the issue.
The issue remains active.
Video evidence and screenshots are attached.
This is a live published island with an active player community.

Steps to Reproduce

1. Launch the published island (8885-3385-3570).
2. Join the same session with two or more players.
3. Play normally for several minutes.
4. Check playtime tracking, eliminations, leaderboards, build permissions and gameplay behavior.
5. Repeat the test across multiple sessions.

The issues occur consistently after the v41.00 update.

Expected Result

All players in the same session should receive playtime progression, statistics should track correctly, eliminations should work in every session, leaderboards should update properly, and players should only be able to edit their own builds according to island settings.

Observed Result

Different players receive different results in the same session.

Examples observed:

• One player receives playtime progression while another remains at 0.
• Eliminations fail to work in some sessions.
• Leaderboards do not update correctly.
• Players can edit builds that do not belong to them.
• Sprint while flying does not function correctly.

The island was functioning normally before the v41.00 update.

Also, my own map is experiencing the progress / persistent tracker leaderboard issue as well since 41.00. For example - One player is permanently reset to 0, while some others can continuously progress their persistent score tracker value for example.

Additional evidence:

The issue is still occurring.

In the same live session, my playtime and eliminations update normally, while another player in the exact same session remains at 0 for all stats.

I have also confirmed additional issues:

• Players cannot eliminate each other consistently.

• Flight Sprint is not functioning correctly.

• Players can edit builds that do not belong to them.

• Persistent stats and leaderboard data are inconsistent between players. and is so important and i cannot do anything with my community!!!

These issues started immediately after the v41.00 update and are still happening several days later.

when it all fix?
