Interesting... HL has done something I didn't expect in the XML. I'll need to make a tweak to the sheet for it.
There's the 'flurry of blows' ability itself (-1/-1) -- the sheet correctly displays this in the 'special abilities' section.
There's an entry on the weapon (+1/+1) -- this is the one the sheet is displaying in the weapon section, and it's correct for melee weapons.
There's an entry on the "rangedattack" element within the weapon (+0/+0). -- I'm not using this at all, but I'm guessing I *should* be using this one instead of the one above for ranged weapons.
Glad you found the problem and I'm not just going crazy. Is there anything I can change by hand to make the sheet correct until you get your sheet tweaked and a new version is released?
