If a game is crashing or textures aren't loading correctly, deleting this file is actually a common troubleshooting step. It forces the game to re-verify its own data integrity.
Never use a third-party "cleaner" tool that promises to remove gfpakhashcache.bin permanently. Such tools often corrupt the Ubisoft Connect installation. Stick to the manual methods described above.

Users rarely know which specific files a mod overwrites until the game crashes or glitches.
