I have started a vanilla 0.17. game with a friend to finally finish up on my achievements, among which is "you're doing it right".
Yesterday, we loaded up the save which was saved with 0.17.33 and started playing it with 0.17.35.
I have the achievement tracked and right now it's at "26k / 42k". In our latest session, both of these counters did not increase anymore, despite me building thousands of things. However, I was able to get other achievements (Golem).
I have kept the old save game from 0.17.33 and loaded it with factorio 0.17.33, there everything works fine. So the bug must have come in by 0.17.34 or 0.17.35.
I can post the saves (both .33 and .35) after the weekend should you need them.
