BP stands for Bridge Plugin, since all bridges uses a bridge plugin to make themselves know to BC any bridge can use BPCore features (and addons).
The Kruge Bridge predates the BPCore so it currently does not make use of it's features. But it only requires changes to it's plugin to start making use of it (ignoring the art side for now).
A problem like this (come to mention it) also occured some time ago, before any public release (say, more than a year ago, maybe even 2 years). It was fixed then. So why doesn't it work now?
