So you are fine with two-headed heroes then?
It's no problem for me, but I think the idea is that everybody should upgrade to 3.08 and WH 1.7, since tons of bugs have been fixed there. I host another game which uses the WH mod, too, and I've done the upgrade, I expect that everyone else should do the same. Having to rename the 1.7 mod to the 1.6 mod is of course not making much sense if you want to restrict yourself to a particular version, so I'll use a filename like "worthyheroes.dm" in the future which I can upgrade without troubles. You're the host, you decide - I don't think that I desperately need the third misc slot.
