Only one private channel working. Other channels sent to <unknown-channel>

When I connect, it connects to only one private channel, @dev-general the rest of the messages from the other private channels show up all in one . (private messages still come in fine).

This is strange, as ircslack seems to know about the channels

[2022-08-19T09:28:49-04:00]  INFO ircslack: User UUUUUUUUU (un) is typing on channel XXXXXXXXX (dev-general)
[2022-08-19T09:28:55-04:00]  INFO ircslack: User UUUUUUUUU (un) is typing on channel YYYYYYYYYYY (dev-internal)

(possibly related to #177 and #178)

More logs, but with descriptions:
