Lately, My automation Has Been exprenicing this weird bug where after a long period of time, the game slows to the point that fixtures and ingame calculations take more than 30 secs to load Then my ram usage spikes past 6 gigabytes and the game Freezes. This happens Both in The car designer and the engine designer. What could this be?
Try out the latest update that was just released on openbeta and see if that helps. Cheers
