This explains your XDV files; it is identical to what I get here (sans
the timestamp). So I guess it was some temporary brokeness, but I’m not
convinced that this is a XeTeX bug, installing multiple versions of the
same font is strongly discouraged.

It should be RawFeature=1058=1; (we now support +tag as a bonus for
features that has OpenType-like tag names, but for numeric ids only
the old syntax of id=setting is supported).
