Description:
Anki 2.1.22, with the JLPT Tango N5 Deck. Even trying to add to one field of one card slowly uses more and more memory until Anki gives a memory error (12 GB system RAM). Mass generation does not work either (same error). Mac OS version 10.12.6 with Anki 2.1.23 generates syntax, but readings, color, etc. do not display (only the syntax displays on cards). See below for error message.
