Enbarr has been doing a lot of looking at the spell and asking me a lot of questions. Well, yelling at me really. <g> I've been doing some research and asked the makers of the spell about their Intentions. I got some answers today.
Dropping things was not an intended design feature. That should now be fixed.
Being unable to tend was not an intended feature. I and several GMs are looking at some possibilities to correcting that. It's not a simple fix, or those that are create other problems. Hopefully this will soon be ammended in one of about 3 possibilities that are available to us.
