Fix Update Related to SCS Changes in ATS 1.55
We recently discovered an issue affecting all files, caused by changes in SCS’s game packing system for version 1.55.
To ensure proper game performance, you must replace all previous files with the updated ones.
The old files were causing in-game stuttering and low FPS, which should now be resolved with this new repack.
Additionally, this update includes several bug fixes on the map based on recent user reports.
