Thanks

Ok, it has nothing to do with a carpet, I'm gonna test some things. Something with a glass-holder chest seems to be broken...

Comment by Enatras

Ok, it happend on a [Pipe] sign using the following items:

[Pipe]
20:0;102:0;374

Changing it to 20:0;102;374 did fix this. Strange fact: On another pipe sign, 102:0 works.

Comment by Enatras

Also happens on a sighn with:

[Pipe]
95:4;160:4

That doesn't make any sense... this ids are correct...
Using the ids in a single way is possible, together -> NPE... O.o

Hi,

Is that the entire error? It doesn't seem possible - as that is occurring at getUnchecked, which is guaranteed not to cause a NullPointerException.

Comment by Enatras

Sorry, here are some more informations:

And the complete stack trace:

Error occurs when putting any item into the start chest (redstone chest)

Comment by me4502

So firstly, that isn't how you specify multiple filters. It should be comma separated.

I'll fix it erroring when invalid enchantments are specified, however.

Comment by Enatras

Facepalm, it is that simple...

Anyway, thanks again and yeah, this should be catched, because all items in the start chest are lost when this error occurs.

Thanks!

Comment by Enatras

Verified and fixed. Safe to close :)
