Within 6 hours of last using my Tartarus V2 and Synapse 4 the bindings of all my profiles have been wiped/reset.
There was no Windows update between these the last time the bindings were present and the next time I used it.
EDIT: Managed to salvage some of them from an old export. So the age old advice, back your stuff up!
This is another annoying issue that has reared its face with version 4.
Report has already been filed through feedback.
