Since the restart on Thursday afternoon, I've not been able to place signs on top of existing signs – is this a known bug with bukkit or another plugin? Or intended behaviour?

I'm halfway through building my mob tower – it makes it a bit pointless without them

yeah I've been having the same problem anyone know what it is?

Bukkit
Ruined me mob trap too

How are you building your mob trap to have to place signs on top of each other?

If you place signs between floor platforms, mobs see them as solid blocks and are more likely to walk onto them (then fall down).

I'm looking into getting it resolved.

Yes, but this should be doable without having to place signs on top of one another. I'm just curious as to why you need to place signs on top of one another.

Again, should be doable without having to place on top of one another.

In any case, Broonie is looking into getting it fixed, so I guess either do it another way, or wait for it to be fixed.

No
I need to place it on the side of another
And yes its still do-able however only works half as well and doesnt work the slightest with spiders
