It seems with the 1.11 version of SlashBlade, Proud Souls aren't dropping when a katana breaks. I have well over 1000 ProudSoul on both a rust edge and Sharpness-White katanas, but didn't get any from either one.

I used a name tag on a zombie, and did get the enchanted Proud Soul from that kill as normal.

Thanks for the quick fix, working as it was in the older versions now :)

Thanks.
