Bukkit

Do you have an error log of what happened?
I just took a random look at my log.. :

Yes, I need to look at making it work in bukkit 1.4.6/1.4.7. Hopefully I'll have time tomorrow/soon.

What exact version of craftbukkit are you running?

I just tried on 1.4.6-R0.3 (#2586) and I don't get that problem, which should occur only when you're so close and in front to the sign, that you would block the placement of a a solid block you're holding while clicking.

So, what version are you running, and what exactly are you doing?

Oh, I just randomly found this ticket and noticed that it was reported by me. In case you ever come across this:

I am not exactly sure in which situation bukkit throws this error, but nevertheless: you could catch it and handle the situation as if no block was found.

That's probably better compared to crashing with this error, until the real reason for this to occur is found / fixed.

@blablubbabc: Go

Thank you for the suggestion.

But as you can see on the plugin page, I've abandoned this plugin. I simply don't play much minecraft anymore and don't have the time for it anymore.
