They aren't patching it even now.
The amount of fixes they are putting in is shameful and discourages from buying their games in the future before modders have at least a few months to redesign their horrible game.
Yes they are. The 1.3 Performance Patch is out, soon to be made available for consoles. The Data Patches are being worked on and will be out when they are ready. Thing to remember, is, most people do not have game breaking quest bugs. I have not had any. However, being an open ended game, things are being done in combos and sequences that Bethesda never imagined. This can cause some quests to glitch or not progress. So, they have to find a way to fix the exceptions without breaking what is working. That takes time.
As for the Editor. if a game patch comes out, or a DLC offers new scripting, then the editor is patched as needed. However, the editor does not really need patching like the game would.
