Hi, Wolfgang— I copied all the fonts to a new document (file attached) and ran ConTeXt. The problem persists. The cause, I think, comes in the lines: \definefallbackfamily[mainface] [mm] [STIX Two Text] [range=digitsnormal, force=yes, features=f:oldstyle] which used to give me oldstyle numerals. bowen1@acbs-mbp ~ % mtxrun --script fonts --list --all stixtwotext yields identifier familyname fontname filename subfont instances stixtwotext stixtwotext stixtwotext /Users/bowen1/Library/Fonts/STIX2Text-Regular.otf stixtwotextnormal stixtwotext stixtwotextitalic STIXTwoText-Italic.otf stixtwotextregular stixtwotext stixtwotextmedium STIXTwoText-Medium.otf On Thu, Apr 29, 2021 at 2:25 PM Wolfgang Schuster < wolfgang.schuster.lists@gmail.com> wrote: > Alan Bowen schrieb am 29.04.2021 um 18:29: > > With ConTeXt ver: 2021.04.28 18:39 LMTX fmt: 2021.4.29 int, I am now > getting the following error on compiling with files that were OK > previously.
