It looks perfect, however for some reason the millisecond number doesn't show.
Can't figure out why. Mega weird. :) I put a colon or no punctuation between ${this.getTextForSeconds()} and ${this.getTextForMilliseconds()}` it will show milliseconds, if I use any punctuation , . ! etc. it will not work.
Could it have something to do with lines 498 - 516 in the plugin? I haven't the foggiest :D
Adding to the weird and wonderful... if I create an event and use the command $gameTimer.getText() it will show the milliseconds after the fullstop.
