There were a number of mods that were found to have some issues, and they've been removed from the regular sideloader mods (found in \mods\Sideloader Modpack) and put into bleeding edge (found in \mods\Sideloader Modpack - Bleeding Edge). Bleeding edge mods aren't updated by default, and if you're using an older version of the launcher (initsetting.exe) you may no longer see the bleeding edge mods in the updater.
Run initsetting.exe, and look for the checkbox labeled "Experimental Mode" in the area with DHH and Graphics Mod. If you check experimental mode, it'll let you download the bleeding edge stuff. If you don't see the checkbox, grab the latest launcher here:

That'll get most of your mods back, but a couple have been removed at a modder's request. Rose's cellphone and pubic hair mods are sorta paid mods now.
BTW, there are a LOT of mods being put into the bleeding edge area lately - it's worth running the updater frequently if you want the latest and greatest (and possibly buggiest
).
