If you go near a do and activate this function

[function usedoor]
ref1=<uid>
foritems 2
  if ((<type>==t_door) 
    ref1.useitem <uid>
  endif
endfor

It was broken in here: 5ffd80b

Specifically here: 5ffd80b#diff-2ca5215fceec7e910be823f77bd2b05c3fc079d18b3ca0d32568aa446a805997L2991-L2996

The s.GetArgDWVal() isn't the user, but object user trying to use, so it fails.

Should be something like this:

// Find item we are trying to use.
CItem* pItem= CUID::ItemFindFromUID(s.GetArgDWVal());
if (!pItem)
  return false;

auto *pChar = dynamic_cast<CChar *>(this);
return pChar->Use_Obj(pItem, false, true);

Or getting char from s.GetKey()
