I currently have the latest version of MO installed, compiling doesn't work. I verfified cache integrity, compiling doesn't work. I tried setting the /32bit+ flag, compiling doesn't work. It was working fine, before Bethesda put out an update, and Steam being Steam, I had no choice in the matter. Anyhow now I'm back to not being able to even add a script, 1. Add script 2. Give it a name. 3. Click ok................. 4. See below. Papyrus Error. Compile results: Starting 1 compile threads for 1 files... Compiling "MDMCustomChairScript"... <unknown>(0,0): Unable to find flags file: TESV_Papyrus_Flags.flg E:\Steam\SteamApps\common\Skyrim\Data\Scripts\Source\ObjectReference.psc(1,0): Unknown user flag Hidden No output generated for MDMCustomChairScript, compilation failed. Batch compile of 1 files finished. 0 succeeded, 1 failed. Failed on MDMCustomChairScript Is there a way of rolling back my CK install.
