Armour stands jump on their own

[MaryDuckAnn]

i recently started up a small private server, and we added this plugin. we've worked with the plugin before and knew how to use it. However ive recently discovered that the last edited armour stand, will often "jump" or move on their own. one moment its were you left it the next its in an entirely new place, sometimes in the middle of blocks or other entities. We do have quite a few plugins, but from our understanding nothing that could mess with this plugin. Hopefully there is a fix of some kind, as working on larger projects gets quite frustrating
