I get all that ops, truly I do. You've put your time and effort into this and you want it to be accepted and embraced by the remaining community. But for the apathetic, especially on this particular issue, forceful implementation is just the way it's going to have to be. If you can't see that then let me be your eyes. Simply suggesting people download it WILL NOT work. Stop wasting your time and just do what I said if you're that hellbent on getting this going. Force people into observer if they're not running 1.41 and direct them to where to get the goods.
The apathy for me comes from the countless attempts (all failed ones mind you) to implement an "anticheat". It's kinda laughable at this point. I can damn near guarantee there's already a bypass for this and if there's not it's just a short matter of time before we're right back to this same conversation, again.
The only hack I've ever been truly concerned with is AA, and that's never really been an issue in this community. So yes, I'm apathetic, and as a lesson to you, you can expect a lot more people to feel the same way, which is why I keep reiterating you'll need to force the issue rather than expect volunteers.
I've been running your 1.41 btw. It definitely feels different but it's not bad.
