Has the last or most recent updates caused the same issue I found with anyone else?

It not the first time I've noticed a setup that worked well before an update isn't good for toffee after it

At the same part of the track the car would suddenly loose speed but the pedal is to the floor( HUD showing it too) so much so using the R18 or Lola Aston between the 1st and 2nd chicane at Le Mans I would loose around 70+KPH for no apparent reason, it would then be ok accelerating out of the 2nd Chicane, Mulsanne corner and then do it again slightly coming down to Indianapolis.
I couldn't hear any more grounding than I would expect (using mostly the same setup I have used for months) but I raised the ride height by another 10mm or so and that seems to have resolved it
