This error can occur after updating the game, downloading saves, installing mods, or even for no apparent reason. Players lose their operating hours when engines, gearboxes or body panels disappear from the build menu.

• 🔄 Damaged save files Especially if you are using cloud services like Steam Cloud.
• 🖥️ Fashion conflicts Incorrectly installed or outdated modifications break the database of parts.
• 🔧 Cache errors Temporary game files can “forget” the car parts.
• 📁 Version incompatibility If you downloaded the save from a newer/older version of the CMS.

It is important to understand that the problem is not always associated with pirated versions – even licensed games. Steam or GOG It can give out this bug. Next, we will analyze step-by-step solutions for each case.

Method 5: Removing conflicting mods

Mods are one of the main reasons for the disappearance of details in the CMS 2021. Some modifications rewrite the parts database, and if they are installed incorrectly or outdated, the game will no longer recognize standard parts. This is especially often the case with:

• 🔧 Modes for parts (turbines, suspensions, body whales).
• 🎨 Texture packs that change the appearance of standard spare parts.

Most often conflicts are caused by fashions that:

• 📦 Have the same ID with other modes (check files) .ini in the fashion archive.
• 🔄 Requires updates (e.g. mod for the old version of the game).
• 🚫 Installed with a violation of the folder structure (files should be in the ~mods, not the root Paks).
