common data inside this RPF file. Since I couldn't manually extract and revert individual files inside an RPF without tools like OpenIV, I realized the easiest way to uninstall was simply deleting the modified update.rpf and verifying the game files (more on that in Chapter 3).Steam whirred to life. It scanned my directory, realized that my update.rpf and visual settings files had been tampered with, and promptly re-downloaded the original, unmodified vanilla versions.
