Well, FTB is still classed as a Beta, so I wouldn't be surprised if updates break game worlds. That's why I'm using it to muck about, get my textures sorted, until FTB is not classed as a Beta.
Yea. I'm pretty much goofing around too, getting to know all the stuff it brings. But some waypoints are on some stuff that I would really like to check out, so I don't want to lose them.
Anyway, I found that Rei's Minimap is saving its config and settings in a separate folder inside the mods folder (...\FTBBETAA\minecraft\mods\rei_minimap\) and the updater deletes that. Making a backup of that folder and putting it back after the update solves the problem.
The updater also seems to delete all the mods you may have in the instMods folder (except forge). Good to remind.
