No mobs spawning on Mob Conveyors.

When using F7 to see a spawnable surface, no red or yellow x appears.

I replaced stone blocks in my manual kill spawner with the Mob Conveyors to automate and the red x'es disappeared.

I already checked to see if this issue was previously reported...

Hello,
Made a minor tweak to the block and changed it's material to rock. I probably derped before.
I set up a vanilla kill box of dirt with just conveyors as the floor then moved away to spawn range.
Modded mobs from Head Crumbs, Player Raiders and Vanilla mobs all spawned on the conveyor block.

I'm considering this to be fixed :) - Next update will have the change.
If mobs are still not spawning it must be another mod causing it.

Apologies for the terrible encoding - but it shows it working.

Hello,
The red X's are just a light level check. In extensive testing I had mobs spawning on the block with absolutely no issues and this method in the blocks class means mobs can spawn on it.

Same problem in Stoneblock modpack

@vadis365 I think the problem is that conveyor is not a full block. When I stand on it I sink in a bit I don't think it has full 1m height.

I'm getting 0 mob spawns

Same issue here, @vadis365 -- nothing spawns on these blocks. I swapped out cobblestone with fans for conveyors and it halted all mob spawning entirely. Appreciate your work -- would love to see a fix for these blocks!

This is a definite problem, an hour of idling with only these blocks as spawn tiles yeild no results. It's most likely due to the block not really being a full block, as mentioned by oliverjanik.
