Research direction

Reproduce the sleep-and-resume scenario with a host and no clients, then inspect the nxdump around NetworkTime__ctor_mD40214D6A925F3027C77DA7051C210F487C0CC55. Trace the suspected NetworkTime loop and verify the game resumes without a prolonged freeze after extended sleep on Nintendo Switch.

Description

priority:high stat:imported type:bug
Description

If you put the console to sleep for a long period of time the console will hang for a period of time.

Reproduce Steps
  1. Start the game or test project
  2. Start a host but do not let any client in
  3. Put the console sleep
  4. Wait a few hours (The longer it sleeps the longer will be the freeze)
  5. Turn the console back on and return to the game.
Actual Outcome

The game is frozen for a certain amount of time. After a while the game is playable again.

Expected Outcome

The game doesn't freeze and Gameplay continue, (Except when playing online)

Environment
  • Unity Version: 2022.3.30f
  • Netcode Version: 1.9
Additional Context

Looking at a nxdump, it seems like the game is freezing in some loop somewhere involving NetworkTime, I did not have the chance to look deeper but I wanted to bring more eyes on the issue. This was the "suspicious" part I found in the dump.
