Not sure how I came to this result, but the editor for one of my tilemaps is no longer able to select tiles properly for paint/erase/fill actions. This is only for the single tilemap, others are unaffected. By changing the viewport in the editor to perspective view, the tile selection cursor is visible again, but it is offset pretty badly from the mouse position.
What might cause this to occur and is there a way to fix it?
