Steam Audio: Erratic Fatal Error with multiplayer PIE

After adding Steam Audio to my shooter project I now have fatal error happening from time to time while starting multiplayer session in PIE.

This issue can be reproduced with the ‘Shooter Game’ demo form the learning tab using the ‘Highrise’ level. Now that i think of it, it might be a scaling issue, the phonon scene might be too large.

UE 4.19.2
