Missing Cylindrical RCS and tiny fuel tank.

[Razor235]

Due to an incident when I had to reinstall the Squad gamedata folder, I lost the external RCS tank and the new tiny fuel tank. No other part from the update is missing. Would someone mind PMing me the files for them?

It would be useful to incorporate a "repair installation" tool with KSP, which hashes all the stock install files for integrity and redownloads corrupted or missing files. Lots of MMOs do this to save bandwidth and time for the user doing a full reinstall

When you get things back to normal, save a backup of those folders to another location, or better yet, to a jump drive. periodically, back up your save game folder which contains your campaigns and ships that you have designed. Save stock install files before installing mods in case you have any conflicts with their installation.

You can just run the patcher.exe, it will update your game to the latest version as well as restoring missing files.

Mine wasn't loading last night. Got stuck at cockpit in the loading bar. Opened stream, hit verify game catch, think that's what is was called, said something about 12 files then it loaded fine. Might work for you.
