Personally, I worked around this fix by setting
Code:
sv_visiblemaxplayers 24
, but that causes issues with the player count in the TF2 server browser being too low.
I may try this plugin after I leave work later today.
Also, does this address the same problem with the SourceTV bot? There are weird slot count issues if you have both bots enabled (Steam shows 0/25 even with both, rather than 0/26 like you'd expect).
