Well at least you got an achievement out of it, rightI don't know how i blew up the meth lab, i didnt know you could. Some guy was pissed at me. Felt like saying some smart ass comment like he didn't explain it or that he skipped all the briefings.

I try to play through every mission offline and read the wiki / steam hub walkthroughs first, just to have a general idea of what I'm supposed to be doing, so I don't end up pissing off my teammates too badly.

Also, I'm getting kind of annoyed at the whole respec cost thing. I almost wish I could have two player profiles or something, and be able to have a unified inventory for all of my characters. And also, Crime.net can diaf -- very definition of form over function.
