When I make a trigger with a timer, and I set some phrases which end the timer early, if I check the Use Regex option, most of the time when I save the trigger, it does not save this option.
A workaround is to make sure you double click each end early phrase - for some reason this will allow GINA to save the Use Regex option.
Edit: This also happens for "Use Regex" on the search phrase. Also fixed by double clicking anything in the search field.
End early text not saving "Use Regex" option
Re: End early text not saving "Use Regex" option
GINABeta (1.0.20.0) has a fix for the Use Regex checkbox in the Early End Text editor, but I can not reproduce the issue in the "Use Regular Expressions" checkbox in the General Settings section; is that the checkbox you are referring to in your Edit?
