Is undo buggered for everyone in FRED, or just me? If it's just me, then I can live without it, annoying as it is, if it isn't I'll mantis it.

For the record, I tried searching mantis, but so far as I could tell there were 0 bugs reported ever, so I assumed something was wrong at that end.

I've gotten the impression that undo hasn't worked since the time that people started to request geomod.

Undo has been dead as long as I remember. In fact it got to the stage that at one point I did wonder if it ever worked or whether it's been a bug since retail


Shove it in Mantis and I'll take a look at it.

I put it in there at some point a few years ago, but was told that it probably won't be fixed for years. I think the bug is still in there.

It used to work fine in retail FRED2 and was quite handy there.

Just get into the habit of saving regular copies, IE
mymission.fs2
mymission_v01.fs2
Mymission_v01a.fs2

That way you can always fall back, every time you make a major fubar.

Yup, but sometimes, even if you save every 20 mins, you could have done quite a lot and only want to undo one change

Ok, found the problem with undo.  It will be fixed for 3.6.9.

EVERYONE HAPPY NOW!!!

I doubt it's a single problem though.  Some things aren't undoable because the state isn't saved prior to taking action.  I found this out the hard way a few times and finally decided to simply not use it.

I doubt it's a single problem though.

It was actually.  It checks for the backup files in the current directory, but it needs to look in data/missions, since that's where it saves them.  If it can't verify that the backup/undo file is there then it just disables undo.  A very simple and easy fix.

Some things are undoable like you say, but the broken undo problem had nothing to do with that.

It's worth remembering that FRED autosaves every 5 minutes or so.

Unfortuately it also has a habit of wiping them out again when you try to use them. If you get an error that requires you to use an autosave you should immediately make copies of Backup.001 to Backup.008. (And I mean immediately. FRED wipes out one of those autosaves the second it starts up).

Never really used undo, I think saving very often is a way to eliminate the need for an undo, if you do something wrong, you just open the previous version. Saving often just crossed my mind while reading kara's post about FRED doing backups. It has a drawback that you cannot go back to an eleven-saves-before version of your mission if you realize you made more mistakes.

If I am doing things that require exact placement of ships (that I used to drag by mistake before I discovered selection lock...) I just used to write down their positions and make them nice round numbers like (1000, -2000, 5000) or something.
