What bugs/issues did you encounter:
What is your FM version: 19.3.0
What is your FMRTE version: 19
Which operating system are you using: mac OS Sierra 10.12.6
I load up the latest FMRTE, load the game, click the mass edit button, filter the ages between 21-33 and try to mass edit everyone's age to 21. It says the filter has found over 44,000 players but only seems to change the age of three or four players. Had no problem with this on all the previous updates, I do this mass edit on the regular - only the latest update has this caused a problem.
Any help would be awesome!
