Openwheel Racing

Stable version from 1.13.0

• Network protocol updated to 10 (REQUIRE 1.13.1 on both server and client, any version async will result in game crash)
• Revived legacy simple terrain checker under better rounded car collision detection zone, ensure part-wise collision does not impact climb/descend
• Added adjustable keyboard steering gain/rate to fine-tune control touch just like steering wheels
• Added car part replacement workstation to replace broken parts
• Added engine status to penalize overheating
• Solidified individual part damage effect: affect downforce/drag/power instead of all power only
• Separated front and rear wing as separate items in assembly
