To fix the clothing IDs in the RedAge V3 GTA5 update, you can try the following steps:
1. Verify the game files through the game launcher or Steam to ensure that all game files are intact.
2. Check if there are any mod conflicts and remove or update them accordingly. Sometimes, mods can interfere with clothing IDs.
3. If you have manually edited the clothing IDs, make sure you have entered them correctly. Double-check for any mistakes or typos.
4. If the issue persists, try reinstalling the game or rolling back to a previous version of the game before the update.
If these steps do not resolve your issue, it may be helpful to seek assistance from the RedAge V3 GTA5 community forums or the mod's official support channels for further guidance.
