The 2 outers were overlapping. Outers can't overlap or touch in more than one point.

YW. It's probably easier to fix with josm. Let me know if there are any others you see that need fixing.

Hi peace2, fyi,
this change broke the wood relation. there is a small gap missing where the wood meets the top of the reservoir. I didn't want to touch it if you are still working in the area.

Thanks for the quick attention and nice reply.

Hi Chronoshift. fixed? It still has a few errors. It doesn't need to be a relation, just keep it simple. Same with the swingset, it doesn't need to be a multipolygon. The park shouldn't be glued to the roads either. It makes it difficult to update unrelated things when they are all glued together. Think of it this way, if you change the park boundary... should it move the road...no.
There are also errors with the church mp across the street, and also the parking at the senior center.
There are similar issues with the park on Veteren's drive.

hi pmarkina. You made one fix, but could you come back and look at this again with more care? You left kerb=lowered on the crossing node. There is also and extra node on the way marked crossing. The way is not marked as a crossing. Also, should it be marked or unmarked?
You could also involve @iskra32, as they are local and could provide details.

hi Woodman! welcome to osm. Good work adding buildings, but quick tip... Press the Q key, it will square the corners on the selected object. Keep mapping!

Hi Mike... welcome to OSM! Looks like you may have accidentally dragged a node in Ark International Church. Can you check and correct? You may want to verify that that is a religious use area, as it looks like residential.

Hi chromogenic, welcome to osm. Which changeset had false deletions? Did you try and contact the user first? Do you have local knowledge? Some of your changes seem fine, but others seem odd for someone new to osm. For example, Why delete all the sidewalks in the new development?

Hi Juliamichael, Welcome to OSM!
Generic things like a pool don't need a name. Same with a bike path, unless it has a name like Lawrence-Hopewell Trail.
Please correct. If you have any q's, just ask, and keep mapping!

Hi Juliamichael8, welcome to OSM! Pools usually don't have names, or personal information, so I removed it. I also shaped it a bit and added a few houses. Keep mapping!

Hi Jbb, welcome to OSM. Thanks for adding a house. I made some corrections, take a look. The outline of the house should be the footprint of the building, not the whole property. Houses don't usually have names, so use the addr:street and addr:housenumber fields for information. There's more information in the wiki.

Hi Cass0902. Thanks for making corrections! Don't map the roof peaks, you should be mapping the footprint of the building. Think what the base of the building would look like without the building structure.
Quick tip, pressing the 'Q' key when you have a building selected will sQuare the corners on a rectangular building. Makes it more accurate, and looks better.

Moving buildings is correct, but you have to make sure the imagery is correctly aligned first. see: osm.wiki/Using_Imagery

in your area it looks like mapbox imagery is better and better aligned than bing (but imagery gets better over time). So, you have additional work to do. Check road intersections and make sure the imagery is correctly aligned there first before adjusting the buildings. Have fun!

Welcome to OSM Mike! Quick tip, if you press the 'Q' key, it will sQuare the building you have selected. You straightened the side of the school, but the building is not squared. Keep mapping!

Welcome to OSM PsuStudent! Instead of making that an area, maybe extend the building (since it is part of the building). Then it doesn't need a name. Also, showing the route to use that window may be more helpful. It seems like an odd location. Keep mapping!

Welcome to OSM Cass0902! You added some great information about the house, but the outline should be sized to be the exact base of the building. I changed it and one other as an example. Can you change the others? Keep mapping!

HI Jocelyne, welcome to OSM!
Thanks for the additions. I made a few corrections. OSM doesn't use abbreviations, like S for South or Rd for Road, so I expanded them. Time is also on a 24 hour clock, so I changed 4pm to 16:00.

If you have any questions, just ask.
Keep on mapping!

hi yadathot. I noticed several conditional relations you created in the philadelphia area. They are in the form relation=no_left_turn @ (Mo-Fr 16:00-18:00)

That seems to show an error in josm.
According to the wiki: osm.wiki/Conditional_restrictions

It seems the correct way should be in the form:
relation:conditional=no_left_turn @ Mo-Fr 16:00-18:00

Can you investigate and correct?
I have also sent an email to amazon escalation.

Hi Kyle, welcome to OSM! I think Mapbox imagery is clearer in your area. Also, try and make the building outlines more accurate. When a building is selected, pressing 'Q' key will square the corners on the building. They look much neater too! If you have any questions, just ask. Or if you want there is a Discord and also a Slack with lots of helpful people.
