Hello im not sure if this is an issue, or I did a mistake, I take the sources and complied it in linux , always OK, I take the data folder of your post, and changed map, I don't touch any like global, compat, etc..
The Issue is very rare, it only affects to Knight and Elite Knight it looks like they don't have damage, , with magic sword and skills 110, to a montser or a train you don't make a hit more high as 180, but then if you make "exori" you hit correctly like 300-400
Thanks for all the work it works very good!
