PCGen is telling me that my PC with a Medium Load suffers a −9 to jump in the "Misc Mod" column. The other DEX based skills have a −3.
If I remove the load in PCGen, it completely removes the −9.
I know Swin applies ×2 to the penalty; but I'm aware of no such multiplication with Jump and can't find anything in the SRD to support this.
Software bug, or have a missed something?
