They are located in the same directory as you would find save games, records, user setting files, no?
I was just playing my first game with 1.10 final and got kicked out. it did display the mini dump message and I am quite sure I clicked 'save'. if it is somewhere else, I'll send you, I can give the description anyhow.
we were playing 3 vs 3, one of ours and one of their had left, theirs just a few minutes prior and I was moving in to kill his planet. moved in siege frigs, wanted to install labs for hcs. did not do much else. cannot tell much about my remaining team mate, what he did in that moment. he was pretty spread out though and not that much in conflict I think.
only other anomaly was that my mouse wheel did not work, but I severely doubt it has anything to do with it.
have it helps, probably not, but you can always try.
edit: forget it, mods can delete the post if the want. I found the file in the temp folder. no idea why, but the search function actually did something good and lead me to it.
