Hello, I would just like to report something that happened to me today. As I was working on a project, I tried inserting an instance variable to one of my classes. Starting from this moment something became very weird. First, some subclasses were not listed as subclasses anymore, then I realised during the execution that allocating my new instance variable was actually modifying another instance variable. I tried digging up a bit and I found out that many of my methods were a complete mess. When browsing with Nautilus the title of the method was for example: "addProperty:key:". However the corpse of the method was totally random with something like that for example: "ient; width: 1. graphic strokeStyle: _strokeStyle" So, reportedly, the name of the method was "ient;" ... Basically I had many methods where the source code was just random chunks of other methods. The funnier thing is that everything worked perfectly fine during execution. I tried to look at different backup images I had to see when everything began to go wrong and I realised I had been working with broken source code for about a week. So if I understand correctly, I probably messed up with the .changes file (I don't remembr how but maybe I copied the .image without the .changes or renamed the .image or i don't know). And now the compiled code is okay but the source code is lost so everything is working fine until the system tries to recompile everything ? Now my question is : is there a way to fix the issue ? I tried exporting the package to a .mcz but I had bugs everywhere. I imported the old working package to an .mcz and tried browsing the differences with the broken one just to manually get back eveything I changed during this week. But I couldn't cause there were bugs everytime I tried to browse the changes. Basically, are all my changes definitely lost or is there a way to get it back somehow (at least the raw source code) ? I know that I fucked up and this is my fault but it would have been nice if something (anything) told me earlier that I did something wrong. I've been adding / modifying lots of methods and even executing the program for a week now and absolutely nothing told me that something was wrong until I tried adding an instance variable. I am in a situation where I actually wrote and "saved" code and now it seems lost... that's frustrating :( Thanks, Matthieu
