Rolluptito, thanks for summarizing some current bugs! It actually helps both prioritizing issues and also to know that the issues are still there and wasn't a one-off thing that resolved itself (they rarely do, but you always have hope ;)
About the rudder-trim issue: I am unfortunately unable to replicate this. Are you 110% sure you haven't touched the emergency trim controls before? They will block the normal trims use for the remainder of the flight. What I did notice is that I was confused at some point and added a emergency rudder trim, which doesn't seem to exist in the cockpit, it's just the normal rudder trim and the course trim (or whatever it is called) for the autopilot. I've fixed that issue, and will await some way to reproduce the non-usable rudder trim issue.
