Within the past hour, a portion of raycast and Region3 API calls have stopped working as expected, without an error. This is a game-breaking bug and we are yet to find a definite reproduction for it. From player reports, we have found that the API calls work for some clients and not others, seemingly randomly. Additionally, the API calls seem to randomly fail on individual clients, also without error.
UPDATE 21:38 GMT - From more information gathered, it appears as if this bug is only affecting the client and not the server.
List of known affected APIs so far:
Affected spatial query APIs should return parts as expected.
From what we have gathered so far, the affected spatial query APIs do not return anything. There is no error, they just return no instances.
