but when I tried updating the more floors mod I got this error:

saying there was a limit to the number of tiles (which this is just a recolored vanilla dirt file)
the mod was working perfectly fine in .14 with the file size 704x32 count = 22
so i changed the file size to 512x32 count = 16
great! no more error until i get this...

I never touched the hazard concrete... when I went to that location all the files had their names reversed so when I fixed the files it loaded up just fine
Heres the log file
