Nugget - so far no-one else has reported any crash issues placing splines. The issue is most likely related to "placing splines in your route", so the solution is to submit a bug report here:
https://n3vgames.typeform.com/to/xRdryu and include a link to your route so that we can try the exact same steps and hopefully get the same problem, which we can then fix.
Euromodeller - you may change your mind when you see one of the features for the next update, which is very much aimed at route builders.
Malc - there will be plenty of beta testing opportunities in the future for non-members, but not just right now. Please be patient and your turn will come.
The current release is a beta and is optional for members to install (as is the official release for that matter). To say the whole concept of membership is about paying to be a beta tester is well wide of the mark. Paying for membership provides for access to a wider range of DLC, an FCT, a 25% discount, previews of new content and, as part of the package, added features each quarter. Apart from paying monthly, it's no different to the way things worked for TANE. You have to pay to get the product, then you can, if you want, become involved in the testing phase.
Ultimately, as Developer and Publisher of Trainz, we made the decision to introduce memberships. As expected, they are popular with a subset of our community. They aren't going away. What they are going to do is help ensure that Trainz grows stronger over time, and that will benefit everyone.
If everyone who owned TRS19 joined, then we could probably double our team size and deliver more new features and content more quickly. Actually, if everyone who owned TANE bought TRS19 right now (or became a member), we could grow the team even more.
Meanwhile, it's going to be a long two years if we continue to see these same negative comments coming out in every thread involving memberships.
