whenever I use snap to grid or snap to angle, the snap to grid moves something 54 units and I think the snap to angle rotates 89
I am pretty sure I have the latest patch

got to File> Preferences and change it there (I have mine at 32 and 45)

thank you I didn't know this and had to memorize all the powers of two in order to make a dungeon

Usually, 32 is good for tileset pieces, 8 for doors and most chests, 4 for just about anything else (especially if you want precision placement of small items). Every now and then, I use 16 for medium/large objects.
