I posted this question in the stupid questions thread but didn't get an answer, so maybe it's not that stupid after all. Basically, I downloaded a lot, and two of the road tiles at the edge of the road are rotated so the trim sticks into the road. But I don't seem to have that particular piece of flooring in my catalogue, only the two dashed ones and the plain asphalt, and the eyedropper doesn't work. I could've sworn there was a cheat to unlock the floortiles that are usually out of bounds, but google is showing me nothing.

It's odd because placing a lot down in a fresh place should give you a new road edge. Meaning this should have fixed after installing and placing. Try picking up the lot and placing it down someplace else. Not at all sure this will be fixable.

Unfortunately that didn't fix it. I might make a backup and delete the road entirely and see what happens if I try again...

ETA: Deleted all the road tiles, picked it up and moved it and now the road edges are fixed! Thank you, I wouldn't have thought to do that if you hadn't told me placing it was supposed to give it new road edges. I do still wonder how they got messed up in the first place though!

Good idea! It had to regenerate all of them after that.

I'm glad you fixed your road issue, but this reupload from shastakiss might be what you were looking for?

Oooh, thank you, I'll try that out - haven't got around to fixing the one in my regular uberhood yet.
