Fat Bloom, fat migration, under tempering? Wonder what it could be (pictures attached)

Remember, it's always time, temperature, or contamination.
Were you able to validate the accuracy of your thermometers?
If you'd achieved success historically, and if you're successful with the new batch of liquor - meaning you're problematic with only a specific lot of liquor - then i'd look very closely at that liquor. Remember not all liquor is created equal - the amount and type of cocoa butter in it can be different - which means that your tempering process and/or final formulation may need to be tweaked as a result. it's also possible (although unlikely) that you received a batch of liquor that had been contaminated with another type of fat. not know the supply chain you're using it's impossible for me to say.
are you receiving liquor, making your own chocolate, and then mixing/molding it? or are you purchasing finished chocolate from someone? if the latter, have you provided the original mfr lot information and detailed problem log so they can troubleshoot that specific lots production information? Do you have a temper meter you use to check temper?
I can rule out fungal issues w/o asking any more questions - it's not that.
Are you soaking the nuts to attempt to degrade phytic acid for nutritive reasons? if so, might i make a suggestion and eliminate that process - there no evidence it's effective (i've done the study), and increases the likelihood of micro issues quite a bit. You may find marketing value in it; however there's no scientific basis for it.
