For me the tasker profiles using the flic plugin seem to "forget" the flic they are coupled with: I usually have about 21 hours since I pressed the flic the last time. This seems to be enough time for the plugin to not work any more.
However, I found that "just" going to the flic plugin in tasker and re-selecting the button and action, then closing all of tasker's windows, will reactivate the profile/plugin.
Of course it would be great if that would not be necessary. It worked before, so there must be a fix. I agree that the version that brought the Hub features was probably the one that broke the plugin.
