Error "AMS drying..." during (PLA) print ? WTH

I am currently printing from PLA… the task is coming to an end and suddenly I get an error message saying “Error occurred during AMS A drying…” ???

What is heck is this? I should point out that I am not drying in AMS, because I am currently printing (and if I am not mistaken, drying and printing cannot be done at the same time)…

… moreover, even if it were possible, I would not do it (I see no reason to with PLA).

… furthermore, I practically never use this function in AMS Pro (even though it can dry), because I find it “awkward” (I use external dryer). The last time I tried the drying function in AMS was about a month ago… but I was really just trying it out to see if I might change my mind (I didn’t – I still don’t use it).

BTW… I pressed “Check Assistant” and it didn’t write anything… I was looking at a blank screen. Printing finished OK, just now …

Any idea what’s going on here ?
