[Remind-Fans] Can't compute trigger - worked before

[Ed Blackman]

I've recently upgraded to remind 04.02.03 (in Debian 12/bookworm) from 03.01.16 (Debian 10/buster).  Some previously working reminders now say "Can't compute trigger".

I've been able to fix most of them to work again, but am stumped by one file.  I belong to a group that meets on Tuesdays.  Most of the meetings are small group meetings, except for *irregularly scheduled* large group meetings.  We also don't meet close to holidays.

I have responsibilities for some of the meetings that I want to be reminded of a certain number of days before or after the meetings.  (The "Contact/Pack/Send" MSG lines are RUN commands in the real version, but I didn't want to repeatedly trigger them while testing.)

Previously I used the file below, editing the "islarge" FSET to contain an "||" of all the announced large group meetings.

With the new remind version, I get "Can't compute trigger" on lines 9 and 10, which are commented below, and the messages don't show up.

Any help appreciated.
