the devs probably have to fine-tune things a little bit, but the next version will probably avoid the "dead sead random standby" when you already aren't already filling your slots
but for now, if you want to eliminate just the "dead seed random standby", which is most likely what you're seeing, just go to Settings > Transfers > General , click the Details button next to Auto manage slots, and change the following:
randstandbychancetable= //every cycle, dead seeds have an independent random chance (out of 1000) of being ...
{
0={ 0={0=0 300= 2 600= 5 900= 10 1800= 20} 1={0=0 300= 2 600= 5 900= 10 1800= 20} }
1={ 0={0=0 300=10 600= 20 900= 40 1800= 50} 1={0=0 300=10 600= 20 900= 40 1800= 50} }
2={ 0={0=0 300=15 600= 30 900= 60 1800= 90} 1={0=0 300=15 600= 30 900= 60 1800= 90} }
3={ 0={0=0 300=25 600= 50 900=100 1800=200} 1={0=0 300=25 600= 50 900=100 1800=200} }
}
make it look like this
randstandbychancetable= //every cycle, dead seeds have an independent random chance (out of 1000) of being...
{
0={ 0={0=0} }
}
