alright, so, i've actually never had this problem on my old laptop and this is... not fun. decidedly not fun.
my map is
-513x513
-greyscale
-one layer
-.png file
-lowercase name Uppercase Terrain no spaces, numbers, or symbols
-alpha channel was never used and therefore never not on
solutions i've tried:
-i've tested the brushes used in it on my testdummy map, which works perfectly (which is scream-inducing enough because seriously only the tESTDUMMY MAP WORKS?
)
-i've copied and pasted the heightmap to another canvas, greyscale, 513x513, .png, even changed the name, and it refused to work
-triple-double-checked that everything is in order
-ran as admin, in case that worked, but nope
also, it's not just that map. the other map i made after i realized "okay maybe this wont work" doesn't work as well.
thanks for reading! hopefully someone has a solution?
have a lovely day/night! be safe!

edit:
okay so i got it working, thank you so so much! i worked for a good 3 hours on this map and i'm extremely happy i can use it because honestly it's one of my favorites! i just had to freaking flatten it, there was probably a bloody patch of transparency i missed x-x regardless, thanks again!
