I found a bug in the "old" Harepacker 4.2.4, so while googling I found out about this project.
Downloaded and tried again, but same bug.
To try the bug:
- open mob.wz
- click on 6230600.img
- select attack1
- tools\export selection (or extract everything)
comparing all the files extracted,
attack1.0.png (0,1,2,3,4) are not equal to the one in the editor.
if I extract 1 by 1 I get the correct image.
this bug apply for many monsters not just this one!
I tried versions 0.62, 0.92, 1.25, 1.54 and all have the same bug.
