Thanks for the suggestion, but we could not buy sludge-slingers yet, early days.
As far as I know, if I succeed in deselecting my dg (a wtf in itself), I can neither use abilities, pick up items nor give movement commands causing him to jog on the spot. That's my recollection at least, which might be flawed.
Well, Uberfix is certainly a good idea. Might even help with this problem, though I don't know how to repro for testing, if at all possible.
