Ok so I noticed a small bug in SkyWyre primitive. It cuts off the last tiles of the sheet when you scroll to the bottom. Maybe it’s just doing this for me, I don’t know. However, if anybody else has this issue, this is how to fix it.

Find:

frmEditor_Map.scrlPictureY.max

And at the very end of that line of code, add:

 + 1

There are only 2 instances of this line of code, so it’s fairly straight forward.
