- copying storage blocks will not copy their filter setting.
- production settings for factories do not copy either.
- using undo/redo will not restore its filter/production setting
How to reproduce:
# place down a storage block and a factory block
# put a filter on the storage block, and a production item for the factory block
# copy paste both and notice that both pasted blocks have forgotten their initial settings.
# also try undo/redo.
