homemade mobarena with 6 invisible spiders. I don't know how a negative distance to those spiders should occur, since i was right next to those.
(i still can't set the tickets title right).

mc1200 spiders and cavespiders with potion inducing.

It disconnects me after hitting a few spiders, and says "internal server error" at the logout screen.

This isn't an issue with craftbook. The potion inducers purely set the potion effect. This is an underlying issue with either the bukkit API, or minecraft itself.

Comment by Martin.Faester

do you have a suggestion for whatelse i can add to those spiders to make them different?

Comment by Martin.Faester

It isnt the potion inducers. I have produced the error only by spawning the spiders from the [mc1200] only. But the error is occuring everytime done so. I can not reproduce this by using /spawnmob.

Comment by Martin.Faester

But it seems to a craftbukkit issue, caused by: CraftChest is not a chest but is instead CraftBlock, gives ticking screen.

How i can produce such error from this kind of spawning, i don't know.

Comment by me4502

That error wouldn't be related. The issue would probably be that there is a bukkit issue when spawning spiders, but other plugins that spawn it don't spawn it correctly or something similar to that, which for some reason works.
I'd say report that error to bukkit.
