I'm not sure what you are saying.
We all know that there are dozens of ways to "play" with Trainz. Some users build routes, some build sessions, some build content and only test their content in the game to see if it works and so on. If you give them a patch to test, they are only testing to see if it improves or harms what they are doing. Not a lot of people want to commit hours to testing parts of the program that they seldom use. Hence the hope appears to be that with a large enough sample of users you hit every aspect of the game. Clearly this isn't working out well as several glaring bugs exist in SP1 that should have been spotted. The diurnal cycle function is broken and weather settings only take effect in surveyor after a save and going to driver and then returning to surveyor. The mini map is also not working as it should. Any route builder should have spotted these bugs quickly as it is hard to build a route without using them. But given that route builders aren't likely to use a beta version as it might eat their route that they have spent years working on I'm not surprised that they were missed.

It's not like us beta-testers have tried.
The mini-map hasn't worked since T:ANE. We complained back then and it was never fixed.
AI got stupid. We complained and the code was reverted back to T:ANE SP2 so now we have creepy AI when it comes to switching. We were told that this requires a complete rewrite of the AI system. This will happen sometime soon(tm) perhaps...
AI flip junction levers for themselves even if they sit on the junction lever and then frog hop over the points without derailing. It looks really, really stupid and is unrealistic. Users can't do that. I complained and was told it's by design. B.S. I called them out on it. This is in 106618 and also occurred before that.
AI are more aggressive with the current version. There's nothing like having junctions set for a particular direction only to have an AI train miles away, with other junctions and signals in between, flip them as the user-controlled train approaches or is on the switch. Perhaps there needs to be a balancing act here, or priority of user over AI when there are user-controlled trains. We've complained. Nothing was said.
AI get stupid over time. They sit there and stare at signals, ignore track marks, and direction markers, or just sit there staring off into space while "waiting for clearance". Pausing, waiting a few seconds, and then resuming fixes the problem temporarily. I reported this last year. I was told it's a threading issue which requires a whole rewrite of code. Soon(tm) on that one.
Splines act weird sometimes. Reported...
Turf-FX does weird stuff. Reported...
Diurnal cycle, I think was reported...
Weather issue was reported early on...
Snowline and seasons issue reported and acknowledged.
I know that N3V likes to keep moving forward and in some ways they have to, but they need to also focus a lot more time on fixing outstanding problems. It's a dual-edged sword and requires a balancing act along with priorities. Unfortunately like many companies and developers, they like to focus on the fun things rather than fixing.
