»[Skyblock] Hostile mobs not spawning AT ALL

So I've been getting into Skyblock on Guildcraft for a day or so. But now I must be missing something. I built a whole dark platform and room with no lighting for hostile mobs to spawn. And absolutely nothing is spawning. I've searched everywhere on the server rules, info and there is no info about any special rules for spawning of hostile mobs (I know people have spawners but I have no idea how to get those). So why are hostile mobs not spawning?
The entity count is always 0/1.
How am I meant to make a mob farm and complete challenges if hostile mobs aren't even appearing?

I'm about to leave and find another server with Skyblock because a mob farm is an essential part of any Skyblock. I already lost my name tagged cow due to some bug in which all passive mobs despawned on the server, could this be part of it???

 

Hello? No reply? I don't see mob spawners going for cheap ($15k+), which is too much to ask for for someone trying to complete the Competent challenges. And also if mob spawners are the only way to go, then how are people getting them then?

 

Well I was asking for anyone to give an answer, anyone who plays Skyblock and has got mob drops, not necessarily admins. But I waited for well over 12 hours while other threads were answered and... nothing. No one answers in the server chat as well. Makes me feel like I'm dumb and missing something blindingly obvious when really I'm expressing my concerns on something that should be part of a standard Skyblock.

 

People are getting them by grinding a lot and also donating

 

So is that the only way? So I'd have to grind up enough money to buy 3+ mob spawners?

 

Same problem, no mob spawn. Could be a problem too high island level (149)?
Otherwise looks like best Skyblock server I've found for now. Could be happy to donate, but mobs spawn absence make gameplay nonsense for me.

 

Make a multi-floored mob grinder to boost spawn rates and make sure you stay at lease 25 blocks away from it. Mine has about 6 floors, which was enough for me to do the music disk challenge. But if your doing the mob loot, it would be cheaper to just buy the gunpowder etc.

 

Don't want to spend lots of time building grinder if no mobs spawns at all (already did this mistake once). For now, built 2 platforms with distance >24, one at level 149 and second one at level 69. Few nights, no mobs. Tried another server - several mobs spawned in very first night. For me, looks like mob spawn disabled on this server. Asked several times in game chat, no single answer.

 

Could you maybe give us some screenshots so we can see if there is a flaw in your design

Strange thing, today I've logged in to my Guildcraft to take these screenshots, and found skeleton on bottom platform. But it was behaving strange - appeared and disappeared when I was moving to-from it a bit.
