I am not sure whether the Pak128.Britain (Standard) developers follow the bug reports on Github, but I get e-mails. In case anyone missed the notification, Neroden has sent a bug report (and fix) on Github here (https://github.com/neroden/simutrans-pak128.britain/pull/1).
I'm not sure I follow what the bug is here?
Ahh, I later found out that this was an accidental repost by another user; it seems that I forgot to note that above. Do disregard my last message on this thread.
