I have the same issue with my server on windows.
Since 1.30 no message that is set in messages.xml is shown.
Worked fine the morning before the Update.

The sound switching sides when leaning left or right on the Motorbike is also weird.
It also stays on one side louder after you went slightly to one side.

Earplugs would be amazing. At least while using Vehicles.

It also happens with roadflares.

If you light one and tab out and back in, it doesn't make any sound for you anymore. So you can hear every other sound around you but not the roadflare.
