FOSS gamedev and creative worlds

*sorry if in wrong section of the forum. if so move and not delete please!*
I installed a mod that spawned blocks in random places, and wish to delete it. the only problem is it leaves many unknown blocks in the map. to add to this another mod replaced some blocks. so is it possible to delete/replace a block mapwide? ( maybe through the sqlite file)

See PilzAdam's clean mod.

I think deleting unknown blocks is only possible in activated areas/chunks. If your problem is only the unknown blocks, you could make aliases. Look at the code concerning 'generate' and 'ABM' and alias the 'new' blocks back into what they were. If the unknown blocks are created in 'air' alias them into air. Probably there are more solutions, but this is one I would try. (EDIT: for example the post above this one ;-) )
