Tbh sort of suspicious looking stuff warrants a look.
Dont take it personal, cause there's a lot of great content contributors that are very giving if they are asked.
Back in the day, M@tt had a dwarrowdelf map that I copied verbatim on my own. I still asked him if it was ok to release it. because it was a copy that I hand created.
He was cool with it. But even he noted how it was exactly the same as his map.
A couple top down comparison pics or allowing a moderator to look at the map is a great way to clear it up.
Anyways, your work is still really great to look at.
