real girder
this 2 shards Dizang shard and Gaozeng shard.
by looking on builds / what was here and there posted. i tryed to rebuild some of them for better understanding.
but could not rebuild it and it took "long" time to see that there are different shard what just look very similar (in my eyes)
in compare to all other shards what are avalible / easyer to different them.
