OBME is an OBSE extension that modifies the plugin format slightly to allow mod authors to create new MGEF records, which is normally not possible in Oblivion.

CBash advertises itself as supporting OBME, but the implementation is actually extremely broken - nothing much we can do here. However, we can make PBash support it. This has come up mostly because Av Latta Magicka, a relatively new magic mod, makes heavy use of OBME and was blowing up the BP as a result.
