plugin issues

on the minecraft pc version the server play.blockville.net is having several issues with plugins since it updated to 1.8 that they dont seem to be able to fix. some of these include buying spawners at their factions shop and every spawner whether blaze or creeper would turn into pig spawners when placed. another issue is faction warps do not work and wolf spawners spawn wolves that cant be tamed at all. the pet plugin also has problems with summoning pets only to have the pet die a minute later.
