Errors in openmtbmap style

[solitone]

Hi, I'm testing your openmtbmap style with mkgmap release 4255 (current version), and I have several errors, for example:

$ java -ea -Xmx1500m -jar ~/opt/mkgmap-r4255/mkgmap.jar --style-file=/Users/solitone/Maps/osm2garmin/openmtbmap --route --gmapsupp -c template.args 
Time started: Mon Nov 26 06:35:37 CET 2018
Error in style: Error: (relations:65): unexpected end of list
Could not open style 
Number of ExitExceptions: 1
Time finished: Mon Nov 26 06:35:37 CET 2018
Total time taken: 292 ms

If I comment out that line, I get other errors, also in other style files (e.g. points). Do I need a specific version of mkgmap or something to use that style?

Thanks & Regards!
