You, not we. I readed a lot of others issues happening just to you.
I export/import projects several times a week. Our own projects and 3rd party projects under our outsourcing services, and never happened this to me. Sometimes, problems are very difficult to manage because just happen in some situations, and you can’t replicate this problems. You, as software developer, must understand this too. NetMake is not perfect and has very flaws, of course, but are not the devil or ignoring.
Don’t take bad my words, I agree with your statement, but sometimes is a problem of attitude and how you express it.
There are a phrase thath sais (sorry, don’t know if in english has sense).
“You get more with honey than with gall”
