What version of Vault are you using? And what does it say at startup?

The Latest. Vault 1.1.6
i Discoverd its a conflict between Lastest ecoCreature and Dynmap

Any other info on what's causing it?

When i kill a creature using Latest EcoCreature

you said it had something to do with dynmap being installed though?

yeah because i needed to update DynMap

v0.25.1
Change log
Fix build FUBAR that resulted in PermissionsEx breaks
Include build number in version (help track dev builds better)
Texture fixes for webs, iron fences, redstone repeaters

does it work now with the dynmap update?

Yes xD

ok thanks, closing this issue :)
