So i'm losing my mind trying to align grid to my custom pdf map which has it's own grid. I make a new sheet, drag the pdf onto the map layer. At first the map is so tiny that it is hardly visible at all. So I resize it to the sheet size, now it fits perfectly but the grid is way off. I align the grid to the pdf grid, and roll20 makes the pdf about 100x bigger than the sheet... About 10,000x10,000. So large that if you try to change the sheet size to match it will warn you that it's going to slow down the program. The tool is so frustrating that i'm about to opt to not even use the grid.
