The online racing simulator
MPR replay - message sounds when client does /i
When watching some replays, there are random message sounds
There is no message typed or whatever...
Anyway here is example of replay, you can speed it up, random sounds will be still there

EDIT:

Aonio sends messages like /i Aonio 157 F 1377

I recreated it on local 0.6B server

Draggo, thanks for finding actual bug

Well, IMO its bug, as sounds are not present in online gameplay and /i messages are not logged
