I backed up and replaced the stock fonts from system/fonts. Replaced Roboto-bold, light, lightitalic, regular, thin, and thinitalic and renamed the new ones to the roboto names. All the fonts were replaced properly after rebooting except for the lock screen colon. In the clock app and the status bar, the colon appears without issues. I don't mind reflashing the rom, it's just the stock Lollipop font bugs the daylights out of me!
