Assetto Corsa | T Rex Mod Upd

The original mod was last updated in 2018. That is an eternity in modding years. The Assetto Corsa T-Rex Mod UPD (often labeled as "v2.0," "Reborn," or "CSP Fix") addresses the following critical issues:

Before diving into the "UPD" (Update), let’s set the scene.

The T-Rex would clip through the track, its animations would desync, and in some cases, the game would crash upon loading.
