According to the console.log, all print packs listed in the gamemode.txt are being loaded.
Are you sure you listed all of them in the gamemode.txt? Did you modify the print packs at all?
Is there some kind of limit?
There is something called a "datablock limit", but prints don't add any datablocks, so no, there's no limit for prints.
Set all the server random stuff to 9999, worked for me when I was having trouble doing events in FNaD
Changing all your server settings to 9999 just allows you and other players to spawn more items, lights, emitters, projectiles, vehicles, bots, etc.
Changing them has no affect on the max number of datablocks aloud. And besides, again, prints don't add datablocks.
