What Type of Bug are you experiencing?

Stability

Steps to Reproduce

Start the project vz_anomaly_4 (see code below). As of v35.00 the connection error happens every time. Sometimes the clients manages to connect, but the placed mesh entities or devices are not visible, the character is frozen until it errors out. Other times it just fails to connect entirely.

Expected Result

It should not fail to connect just because of some deeply nested entities with some long names.

Observed Result

Here are some example error logs:

FORT-902590 has been ‘Closed’. We’re unable to reproduce this issue.

@Flak was the issue closed because it couldn’t be reproduced on a future build or did the team failed to reproduce it with the provided project + public v35.00 version? I specifically made sure the project is in a state where the issue can be reproduced.

I have never gotten so many networks errors before until I started using scene graph , I constantly get

LogValkyrieRequestManagerEditor: Error: Failed to handle connection attempt (Network error occurred when connecting to a server after matchmaking completed.

Worst part is I can’t even launch session again because it’ll just get stuck, only solution I’ve found to start up a session again is restarting my laptop and opening everything. The project is very small and has only 2 simple components on it
