it was fixed some time ago. ( thank you cannon ) - it had been fixed a long time ago already - but that fix was nullified by the "custom lights" hack.
anyway - the new persephone ( 4.86 ) won t have any genuine bugs anymore. ( and is considerably weaker than the new juggernaut, which is - after all - its successor )
edit: oh - but on other servers - the current persephone is still bugged. - so the other servers need a cannon, too.
