I hope I will do it short (!), but basically, if you find issues, and if you are paid to fix issues, you got 2 paths :
Keep the fix for you, and try to sell it, over and over. Keep quiet about it.
Share with the pack, if you think it is worthy and can help people to avoid to pay for such fixes.
aCis goal is to unite everything (my work and community shares) in a single piece of project, which is less and less buggy, and whom revisions aren't fixes of each other (which is often what happen to projects - L2JFrozen for instance).
About "why so much issues in 2019, after 10y of development", some ways to answer :
L2J IL is extremely bugged, and we start from very, very far. It's really a basic answer, but extremely right. As a basic user, you probably got no clue about what I had to fix. Some huge parts had to be taken from postL2J versions (TradeList, Multisell, skills system, etc).
L2J organization is clunky, and some time was spent to make it more organized. It's stupid to say, but it takes some time to write a Javadoc.
I care about every single aspect of the gameplay, while most project owners don't.
Scripts folder, while fully bugged and in need of fixes, took me a huge amount of time. Most of projects never care about them, or they simply copy-paste my work (L2JHellas, for instance, and maybe Mobius IL - ? I don't remember well so spare me on this one ?) which obviously speed up things for their projects.
I deny bug fixes until a L2OFF test is done and valid the behavior.
If I got no bug report, I got no bug. So I can't fix it. It's also extremely simple to understand, and that's why your behavior is problematic.
If I got a bigger plan for a bug report, than it's delayed, cause I know I will lose my time. So some issues are simply kept alive, the time a bigger rework is done (case of SpawnManager and all spawns related things).
About the slow development, some ways to answer :
I'm mostly alone to develop. That's a simple fact. I'm perfectly aware I'm the biggest bottleneck, and unfortunately there is nothing to fix that issue, except cloning myself or recruiting some enough talented guys I don't need to backup and can code the same way I do.
I'm a human, and sometimes as a human being I need a break. It can be ass-long, but it is needed. Otherwise, you simply burn yourself. Doing something you don't like is the best way to give up. I'm still here after 10y. I can't say the same about 95% of projects out there.
Community shares need to be reviewed, tested and checked by L2OFF. Most of them are bugged/malfunctioning/not retail.
L2OFF IL itself is buggy. Some reports are wrong at a time, and valid at other times. It's really frustrating sometimes to get one report saying one thing and few months later getting another tone, while both tests were done on L2OFF platform.
Some infos are simply lost. I must dig to official patch notes to find informations. It's very time consuming.
My own politic about heavily testing things is also time consuming. But it saves time in the long run, avoiding to fix one thing over and over.
All in one, simply share the bugfix, and there is no bug anymore. No need to complain. You are rewarded with Customer rank, or Inner Circle after a time. You help multiple dozens of people (actually 90+) in same time. You help free users - even if it's delayed for them, it becomes one day or another usable by all.
Finally, if you really don't like aCis (or me, cause it's generally what people don't like but they prefer to attack my project even if they use it) :
Provide a better alternative than aCis to people. According to your first topic, it looks like you are perfectly able to do it, and we will see if you can do it better with the same material (L2J base).
Use another project, since nothing stop you to use another pack.
In case you're a paid developer : don't provide services for aCis. Simple !
But I already can tell you this : each pack got its own issues and so you will end with different types of issues. No matter if it's free, or you paid 1200$ (and if I say that, it's because I asked someone to test 2 behaviors on L2Scripts IL, and both were as wrong as L2JIL).
I hope you all appreciated that analytic point of view !
Regarding aCis itself, it's :
550+ bug reports archived (only reported issues, not including my own fixes)
50+ public shares committed
400+ "customers" since 2011
90+ customers at the date of 16/09/19.
A community of 4k+ topics, almost 4k members and 34k+ posts.
Unique self coded things and "courageous" reworks (because I could simply go full "fuck themselves" and deliver you the same 2007-2010 crap that is still existing here and there ; but I believe I got some balls to bother about some game-breaking things like knownlist or movement, and I could be kudos for that).
If that was that bad, it wouldn't be used. I hope ! :)
