I responded to a post about a lash-up issue coming out of PFA and squeeling. While I was trying to recreate it my remotes messed up. One time the lead PS3 Drefuss would not move yet would respond to sounds and lighting directions. The tail PS2 Drefuss did run?
Today a lash-up build in an older remote kept reverting back a screen and would not allow me to select an engine to build with.
I switched to the phone and both trains ran fine?
I will research more and report further.
