"all the previous versions that I had access to"
No, you didn't. There are potentially hundreds of snapshot versions sprinkled throughout the forum which is why I told you to be specific. What's so difficult in saying "every 1.7.10 version listed on the Download page".
"If you do not have any interest on testing bugs how can you call yourself a dev?"
Since the previous pre-release I've already accumulated a list of 14 things which I'll be looking into today, so I gotta keep each item as small as possible. Given there's one person (me) maintaining the RM with the skills to fix bugs once they've identified them and a lot more people (most of everyone reporting bugs) who can follow simple instructions, I'd like to make the best possible use of the one person's time (because it's the limiting factor) and defer as much of the unskilled work to people who can't do the skilled one.
Also, you do realize I'm not getting paid for this, right? Any time I put into maintaining this mod is my own and I've got lots of more fun things to do.
"but in my opinion you should try fixing it if you want to keep putting more versions of 1.7.10 out."
Given those options, I'll be abandoning 1.7.10 then, would that make you happy?
Or does trying and failing because of lack of time already qualify as "try fixing it"? In that case, we're good as that's what I've been doing the whole time.
