Probably stating the obvious but currently if you have trinkets giving a stat bonus that brings it to a new threshold for a bonus to skills (for example if you have 75 str and a +5 str trinket) there seems to be an issue any time you relog or die that the skill bonuses are calculated off of your base stat and not including the trinket bonus. Sometimes it will reset to the proper amount and others it does not. Hopefully this is on the list in the bug fixing / polishing phase atm.
