Launching AMS2 via steam then attaching to game via SC4 causes SimVibe application to close. Disable shared memory in AMS2 (PC2 UDP 1) exit and re-launch AMS2 - re-enabled shared memory and re-launch - SC4 continues to crash.
Launch options in SC4 set default using SimVibe AutoDiscover. Cloud tuning Game discovery used to work after a couple of reboots, now impossible to use.
