I'd really understand this if we were talking about intermediate or something but considering that by the time you really need to remember the turn order in most games your opponent has 3 or less worms I cant really see how thats's difficult to memorise by simply remembering the positions of worms on the map that have played and the ones that havent.
as for graves etc dont make me laugh -.- if you're aware that shit like this might happen you make a mental note and play on, like you do in roper when you set off to get a crate, lets not make a huge deal out of something thats not :/
that's my opinion ofc
