This fix addresses the fatal error upon trying to load this map.
Note however that R_ObjBlockmapClear is causing serious performance degredation when attempting to play it. The ObjLinkBlockmap should be re-implemented using the sparse Gridmap design employed by the other blockmaps to minimize the number of blocks needed. These non-null blocks should then be linked into a chain to avoid traversing the whole grid during a clear.
