Found another problem in 4.26 
Sometimes when exiting the shipping build of the game, the process continues to run and has to be manually shut down.
I thought it was a Steam related problem, so I rolled back to STEAM SDK 1.46 (From 1.50), which didn’t work, then I just ran the game without Steam open and the same problem occurred.
I’m going to roll back to 4.23.1 today and I’ll deal with the bugs it had until a more stable build comes out.
