Continuation from https://mods.factorio.com/mod/dimension-warp/discussion/6902e5d5a8da210ba60a6692, basically the warp gate doubles as a teleporter and accumulator, so when solar productivity swaps it for an upgraded version dimenions warps assumptions break, from what I understood. Seems the Dimension warp author suggests the fix is to have this mod ignore the warp gate entirely for upgrades.
