How did you *use* the GI cache files? It can be a bit more complicated when rendering cube face images. You need to either render 1 large GI cache in *spherical* camera mode, or render out your GI caches for *every cube face* sequentially (i.e. camera direction #1 outputs gicache_0001.gic, camera direction #2 outputs gicache_0002.gic, etc.), and then do "equal blend within range" using all 6 of the .gic files, specified as a frame range wildcard (%04d for example).
