I just tried in both 2020 and 2024, and everything seemed ok. I think I have the latest version: SP3_v2.0.5_241120. Mind you, I just loaded "ready for take off - no failures". I haven't flown the plane in quite some time. The C310 does allow for fairly complete random failure options. Do you have the failures option set for on?
PS: oops, sorry, just realized you don't have click spots either, which shouldn't happen. If you didn't before, maybe try loading ready for take off, and see if that makes a difference.
