Summary
Since the v41.20 update (July 16, 2026), my Zone Wars map (32-player) has started crashing, and it doesn’t appear to be an isolated case tied to Epic-wide issues, since other Zone Wars maps I’ve checked are running fine.

Steps to Reproduce
- Launch Session (works fine solo or with multiple players)
- Play normally — no specific action required (no building, no device interaction)
- Crash occurs, most often mid-to-late match, but in more recent tests it has also occurred almost immediately after entering the session
- All players in the session crash at the same time (tested with multiple players online)
Expected Result
The session should continue running normally without crashing.
Observed Result
The client crashes for all players in the session simultaneously. No crash occurred at all before v41.20. Re-publishing the project without any changes temporarily resolved it once, but the crash returned on the next session. Rolling back to a pre-v41.20 revision did not fix it either.

Additional Notes
The map was built by a third-party developer, so I don’t have full visibility into every device/Verse setup, but I do have Revision Control access. The editor log did not show a Fatal error, but did show a large number of repeated warnings related to Teleporter_V2 devices (AttachTo / static component mismatch) at session start. This crash has been observed across multiple platforms (PC, PlayStation, Switch), which suggests the issue is not platform-specific but likely related to the map/session itself. Happy to share logs if useful.
