Before the update to 1.20 I got a crash.
The settings are still default, so "rail" is unticked.
I gave the rail line names with LineManager syntax whatoever as a reminder and for later use.
There were two lines with a rate of 200 each and "linename (R:200)" in the line name.
After the industrie leveled up to a rate of 400 I edited the line names and changed to "linename (R:400)".
A few seconds later the game crashed to desktop.

Could it be that the code does not like the syntax in rail lines when rail is unticked in the settings?
