A new business opened called Spectrodulce. The address points to the spot on the map, however I did not see it when I went past the spot in the real world earlier today. I will investigate later when I have a chance, but if someone in the area knows exactly where it is and can add it, the address is:

3926 William Penn Hwy
Monroeville, PA 15146

It looks like Clairton Road has been split into two pieces here. I cannot figure out how to merge these, and I cannot delete one to extend the other through to where it should be. Can someone please take a look at this and see if there's a way to merge them properly?

There is a point here, visible with the Map Data layer enabled, and also visible in the editors (iD, Potlach, probably others), that does not belong here. It is marked as a Building called "Easter Seal Society Western Pennsylvania". I can personally confirm that it does not belong here, however that does not mean that it doesn't exist in some obscure part of North Versailles that has somehow escaped my notice. I'll leave it here for someone to fix who actually knows if and where it exists.

There are two churches here that appear to be referring to the same point. Also, I can personally confirm from going past this point on an almost daily basis that there is only one church here. I do not deal with churches, and I do not know anything about this church, so I will leave merging these points to someone else who is willing to look into it. Feel free to mark this as resolved when you are done figuring this out.

Building addresses are slightly out of sync with map. My home address shows as one house down from where I live.

There is a street here which I have recently added to the map. I have walked past (and along) this road many times and have never seen a street sign. If someone knows the name of the street, please add it.

There are two buildings here that are part of Great Valley Shopping Center and they both seem to be marked correctly in iD and Potlach, but only one of the buildings appears in "normal view" (i.e. the non-editor mode of openstreetmap.org), and the same can be said of apps like osmAnd. It seems the other building is completely ignored in viewers even though they are correctly marked in the editors. I can't figure out how to fix this in iD or Potlach, so I'd appreciate if someone can help with this.
