Error code "NM14" when joining Weekly Event race in GRID Technical Assistance Posted December 30, 2020 · Edited January 2 by LebosRacing At least for me it seemed to have improved with the patch 1.13 (stating Changes have been made to reduce the chance of being disconnected from a game session. ). Only one case of NM14 in November and since then no problems anymore. Also using Windows 10, DRX 11. EDIT: I shouldn't have said it... Today (2.1.) NM14 again when trying to join the weekly event.
