If you would like to weigh in with any other details, that would be good.

As soon as I have time&energy, I'm planning to give you some coding help, so I thought I might as well start solving one of the biggest problems first.

And they've moved it to "won't implement" :-(

I guess we'll just have to get everything else working flawlessly first.

Won't implement is won't implement and not later.

Unless some rseding-level coder with interest in it gets source access and adds it.
But chances are low for that.

I'd have thought if we can get train teleporting working flawlessly then they might reconsider.

We will see. At the moment I don't have the concentration left. Last man standing of my team. The rest is on vacation. Should get better in a week or so. Then I will endeavour first to fix all the currently know bugs and probably rework some things to make them more stable. At the cost of performance most likely, but stable and a bit slower is better than crashing fast.
