Manually changing IDs

[jondonnis]

So I updated BuildCraft to the latest as said it works with 1.5.2. Loaded a test world and seems OK with BigDig, no crash. Load my saved world and get ID miss-match I looked at the forge log and see this:

2013-06-01 22:06:49 [FINE] [fml.ItemTracker] The difference set is not equal: value differences={1047=(Item 1047, Type buildcraft.silicon.ItemAssemblyTable, owned by BuildCraft|Silicon, ordinal 0, name null, claimedModId null, Item 1047, Type buildcraft.silicon.ItemLaserTable, owned by BuildCraft|Silicon, ordinal 0, name null, claimedModId null)}

World carried on to load fine. I'm looking around Item SubSets and found it:

Will this cause any issues? I haven't built one of those nulls yet which is actually an Assembly Table.
