On the main Simutrans site. I was advised to join this site.
Sorry but I do not speak or write the German language.
The bug I am reporting with a save file.
Is to do with posssible scheduling errors.
That's a misunderstanding. This here is the German Simutrans Forum. "Simutrans Germany" refers to a different website, in particular the file upload service:
files.simutrans-germany.com. Not directly affiliated with the german or english forums.
