Can't get PackFileManager to work...

[briny_norman]

Maybe I'm just an idiot, but when I change some stats with the PackFileManager nothing changes in the game.

I open the patch.pack file, change some stats in the unit_stats_naval table, save and quit.
But when I start up the game nothing's changed. No values have changed on any unit cards and gameplay stays the same too (I'm trying to make ships harder to sink...).

Am I doing something wrong?

did you unpack them repack after you made the changes and i think you need to apply it to main.pack to

No, didn't unpack.
Just changed the value in the manager and saved.
I'm using PackFileManager 1.9.
Didn't think unpacking was necessary.
I just tried using that feature but my computer just hangs when I try to unpack a file.
