with the last update i can no longer hold down the year bar to go by the decades. also, the end of the crankshaft sometimes flashes white. another thing, with the last update the parameters for valve float was changed and now it just feels like theres always too much valve float, especially when making older engines with pushrods.
Yes, known bug, will be fixed soon 
I don’t know if this is the case for anyone else but I have updated (1109) and dispite the 10 year step being listed as fixed in the notes it still doesn’t work for me.
True, this was fixed in an internal beta version but seems to have got lost somewhere in between. I posted that yesterday in our bugtracker already.
