Ok -- so I think a lot of the items in Is and some elsewhere, are displaying incorrectly. I'm seeing prices as 1 penya and 4 penya for a lot of items that should be 10k and 40k. I can purchase the ones that don't end up listed at 1 penya, but not the ones that do.
I've tried:
1. Using pserver v14 sources, deleting world, patching, letting patcher run, launching.
Result: Game crashes before launch.
2. Using official v15 fully updated sources, deleting world, patching, letting patcher run, launching.
Result: Can't purchase 1 penya items which should cost 10k.
3. Deleting Flyff.a and re-running launcher.exe or Flyff.exe (instructions say launcher, so I usually start with launcher, then try Flyff. Flyff appears custom skinned, launcher does not :/)
4. Deleting data.res, dataSub1.res, and dataSub2.res, rerunning patchers, launching.
Result: New background on login screen, problem still exists.
5. Renaming Char folder.
Result: None, not regenerated.
6. Renaming Item folder.
Results: Not regenerated, no items appear, cool trick if you want to scare your friend into thinking they got hacked
just remember to tell them eventually
7. Renaming World folder.
Results: Not regenerated, didn't try launching.
I am currently re-downloading the patcher.
