We’ve encountered an issue affecting our game Emergency Hamburg where we’re unable to create a Luau Heap Client snapshot, both in Studio and during live client testing.
Details:
- The issue appears to be specific to Emergency Hamburg. We’re able to create Luau Heap snapshots without any problems in other experiences and places (that are NOT related to Emergency Hamburg).
- We’ve confirmed this behavior persists even in older versions of Emergency Hamburg where snapshots previously worked without issues. This also affects different experiences (for example each developer has their own experience with their copy of the game, this is also affected).
- For example, we have a version saved (untouched for 3 months) specifically for performance testing, where Luau Heap snapshots were used extensively in the past. This version is now also affected.
- Local copies of the experience or copy outside of the group also fails to create a snapshot.
- This suggests the issue is not caused by changes on our end, but may be related to something external, possibly at the engine or backend level (maybe some flag was flipped for us?)
- This affects all our developers on different client versions.
Reproduction:
- Open Emergency Hamburg in Roblox Studio or join the game as a client.
- Attempt to create a Luau Heap Client snapshot.
- Observe that the snapshot fails to be created (the game lags for a second as with normal snapshot creation).
- Try the same process in a different place or game (that is NOT Emergency Hamburg) – it works as expected.
This was taken in the main game place, which is live for players, this place was not updated for a while and had Luau Heap working just fine before that.
Expected Behavior: Luau Heap snapshots should be creatable as they were before, especially in older versions of the game where they previously worked.
Actual Behavior: Snapshots fail to generate only in Emergency Hamburg (including all versions), while other games are unaffected.
