Latest Version - v2.23.3
v2.23.3 fixes:
- When erasing track that also has platforms, foot or level crossings or other (blue) locations present the first right click just erases the platforms etc., leaving the track intact with its length, speed limit and preferred direction(s) in place. This makes it easier when only those elements need to be erased, as it saves having to replace the track and reset lengths etc. A second right click erases the track.
- During operation missed or late passes carry no score penalty (this has been the case for several versions), so the ‘ERROR’ prefix has been dropped in the performance log to better reflect this.
- A ‘maximum lateness’ entry has been added to the performance log summary.
