Bug unity 2018.3.6 no player logs

Hi in above build I no longer get player.log on development builds. Unity produces the folder structure, .config.... and analytic folder and editor directory with some files like config, values , c,d,e. But no player.log. It makes finding a bug in a development build that doesn't show in editor very difficult.
Can anyone advise? Thanks

 

Hi this is a bug, traced it to company name directory unity puts out as you have saved name eg KnobbysCompany, however the log file tries to write in all lower case eg knobbyscompany.
