Yes, so for example...
It's withdrawn a Glory (4) and equipped it, four tasks later the Glory is now at zero charges. However it doesn't seem to recognise this, so when it finishes it's fifth task, it's unable to use the glory amulet as it has no charges left. I've only noticed this happening with Slayer Master Vannaka.
This is where having a teleport Tablet to Varrock or somewhere could be handy, so if the script struggles to find a way back to Edgeville, it can simply click the tablet and be somewhere familiar.
