Quite often with the new update to A6 I find more and more, this workflow effect happening, even to the point of losing entire files.
It seems the engine no longer gives every error report at the time a full-on development session is in progress and I wonder if its to do with the page file being so crammed up that it effects final writes from the page file to the programm application.
I find this only happens with Game Studio though so I cant help but think that maybe DX is also part of the problem.
So yeah, I have these issues too and...
From one noobs to another, hang on in there man, its not as bad as it may seem, just have more breaks more often to free up dlls and memory usage.
