shroudBNC Board

Hello
There is a problem: after connecting to the BNC account the channel has nicks, although at the moment they are not online. After rejoining the channel everything is fine. In my opinion it is a cache that stores the nicknames of people who were on the channel before disconnecting from bnc.
Can you please tell why this might happen and how can I solve this problem?
P.S. sbnc 1.2, debian 5, tcl 8.5.3

The problem is still relevant
Can anybody tell how to solve this problem?

This may be a Bug, yes.

Since i've never had this problem, i can't tell you if it's fixed in 1.3

Its not fixed in 1.3 i have the problem
