[1.5][SMP] Mêlée turtles not attacking properly

CC Version: 1.3 Client & Server Derp 1.5
MC Version: MindCrack 8.1.1 (MiscPeripherals 3.1)

Bug: From a mob spawner, mobs that land in front of the mêlée turtle are not killed properly after a 20m (est.) drop. They simply sit there. Mobs are pigman, witch, shroom and wither. The codes are below:

while true do
turtle.attack()
turtle.suck()
end

The screenshots of the kill-zone are below:

Split into new topic.

Someone else had mentioned that they were having trouble with melee turtles attacking, but the issue was resolved by using the top of the turtles as the attack surface rather than the front.

Edit: Also, I have a difficult time believing that you're using ComputerCraft 1.3. :)/>

Ah, that's weird. I'll try that. Although it should be the front as it did work before the 1.5 update. And yes, you're correct - a massive derp on my behalf - I am using 1.5 :)/>

Hm. This is inconvenient. I was using a pressure plate to throttle the mob flow, which I can't do if the turtle has to be underneath the mobs. I guess I will have to put the redstone signal into the turtle program.

I think I will go ahead and move this over to Bugs, which I suppose was your original intent.

Please test this out in 1.51 and let us know if this is a problem, and post it as a bug in the thread if it is.
