We are investigating this one hardcore. We have made a fix for "floating bales" and hope this will also affect and fix this issue in the upcoming patch 1.3. We have not reproduced it since and it seems to only be happening on console so we can't really get a log file from you guys. If anybody has found a die-hard way of reproduction as in start the game, do this, do that, issue happens EVERY TIME then PLEASE let me know.
It does not seem to matter what tractor you use, only the square bale presses are affected (has apparently happened with both basegame Kuhn press as well as the New Holland press). If you have had this happen on PC then please also check if you can make this happen in the 1.3 Beta patch - but it seems to be on console only.
Feel free to spread this message to the other posts as well - any help and information regarding this is very much appreciated.
