Automobilista 2 has now been updated to v1.0.1.1 - this is a hotfix to complement the latest release with some further improvements & fixes to new features / content.
Regarding Spa-Francorchamps DLC
We apologise for the ongoing unavailability of the standalone Spa DLC on Steam - we have already requested Valve´s support to address it and expect it will be sorted soon (by Monday at the latest). In the meantime it is still possible to acquire the track as part of the Premium Track Pack, or the complete 2020-2021 Season Pass.
V1.0.1.1 CHANGELOG
Added International GT3, F-Classic Gen1, GT1 championships
Enabled multiple random weather slots in championship seasons
Disabled formation lap for championships ith rolling starts
Adjusted AI performance through various corners for better balance vs player
Slightly increased Bathurst AI Grip values
GT1 physics revisions: Adjusted engine compression curves & added throttle map for all models; adjusted default coast differential setting; Slightly improved Mclaren F1 GTR engine & center of gravity
P1 class physics revisions: corrected G58 weight distribution; added 10-15kg to AJR cars for better BoP accross class
GT1 AI callibration pass, GT3 AI rolling resistance adjustment to better match player straight speed
Adjusted roll bar rates in Group A cars (requires setup reset)
Greatly reduced values for AI simulated times when skipping session (logic appears to have been broken in one of the latter AI code changes so this is a paliative measure to help prevent AI doing much faster times when skipping session until bug is addressed)
Time Trial mode now includes all the latest content."
