The feats can be found in the /System/data folder, depending on which tool you are using. The files are in XML format. I hope that helps.
As for the disappearing equipment .. that appears to be a bug. I can fix that and put it in the Beta repo soon enough.
edit:
The bug looks like this.
Original code
Code:
if node._get_tagName() == nodeName: node.text = value
The fix looks like this
Fixed code
Code:
if node.tag == nodeName: node.text = value
I'll put it in the repo as soon as I can.
