I understand there is an issue where players are unable to update the game because the "Update" prompt is not showing up on the pager. I haven't taken my time to search around to see why this is happening, or if other games are also experiencing the same.
As a temporary workaround, you may open up the BYOND pager, open the Pokemon BlueFire tab and click Uninstall. After that, you can just hit Install again. It should install the newest PBF version. This will not affect your save file since it's located in a different folder.
