Can't save script

Questions & Answers
1

Hi again everyone,

I’ve been running into a new issue since upgrading to 4.3, and didn’t know if it’s a known problem / bug / user mess up. Often, when I make an edit to a script and want to save it monodevelop will spit out an error and not let me save. If I save under a different name, all’s well, except that then I can’t delete the name of the original file and change the name of the new one to the original in Unity. Am perplexed as to what’s going on. Any help is appreciated. God bless.

So, the answer is kind of silly. What happened is that MonoDevelop now allows the same script to open twice, in two tabs. Trying to save one with it open (and not changed) in another tab makes it go berzerk. There we have it. =)
