Patching the game Makes it entirely reinstall.

[Jaquecz]

So after Patching the game PSO2 Tweaker believed that the entire game was missing and tries to redownload the entire thing, it's getting annoying to deal with.
Help would be great at this point wont lie.

EDIT: Actually it does seem to redownload THE ENTIRE thing.
Or something like that because all the original files are suddenly missing.

No apparently the entire game is still there, every single damn gigabyte, but they all have an Isaver extension.
Every single file.
WTF IS GOING ON.

Yesterday people said that there's issue with Tweaker "new-method" patching and it'll redownload the entire thing instead of just required packages.

If you're not using story patch, it is safe to patch just using JP launcher right away to avoid this issue.
