This suggests that you were running with a configuration file different
from the one you're using post-reboot; when Exim handles incoming mail,
it re-reads the config so this is a case of different binaries using
different paths. Perhaps some boot-time start-up script auto-generated
a config file in a different place from the one you normally use and
that was preferentially used? At least one OS patches Exim to have a
list of config files to try to use.

The procmail Router probably has no_verify on it, so that it's not used
during address verification and a later Router, typically named
"localuser", is relied upon for that.
Whichever is the first Router to *not* have no_verify on it, which
handles the given address, is the one which also needs
local_part_suffix/local_part_suffix_optional.
