Hi everyone,

Thanks for all the responses on these very naughty skeletons. I think my base is haunted myself

I believe you Star, really I do!!!

I would just like to confirm that the slabs are bottom half slabs and are placed on full blocks as it is down at bedrock.
There is one stone block followed by a half slab on top of the stone block. To see evidence of this on the video you can see the height by looking at the torches on the blocks beneath where I haven't placed slabs. Had they been top slabs you guys are right in that mobs could spawn as top slabs behave as a full block and could take redstone dust.

The assumption that this didn't look like lag is also correct as when the creeper spawned it was walking at normal speed while the skeleton was going crazy. They spawned a few seconds apart so it was a handy comparison. Sadly I don't think I have video of that occasion.

Handy to know that they can spawn on furnaces and workbenches. Thanks Frost for that info, I was never sure and I really should have checked with the wiki but never got around to it! The item sorter is still being built but will get a dose of half slabs on the furnaces!

My thoughts are that this is not down to the server itself but goes back to the original mojang code as it is an NPC oddity. I have seen skeletons spawn next to torches too and these I think may be the abnormal odd ones. If there is a bug in the mojang code, it then of course gets passed on to spigot and paperclip server code so not much anyone can do as it is so infrequent.

This is not really a problem to me as it has only happened a few times but thought it might be interesting to everyone.

Thanks again everyone, have a great day or night depending on your time zone!
