Solution for people who may have a similar problem:
" $('#Logs .log-line').slice(13).remove(); "
By default it says slice(500), adjust this number according to your needs. 13 was enough for me.

clicking the log id often makes the complete log disappear

What version of BAS are you using?
In what circumstances does this occur?
Please attach a test project that replicates this here or in a forum PM.
