Hello @jjjj and sorry about your disapointment.
I do not see anymore the minionSlayer quest in your account data, which means for me it have been achieved.
I think I can retrace history in here. Around 15th February when I saw players reporting this problem, I resolved the minion slayer enemies count calculation problem and pushed these modifications on our development environment.
All our code modifications and corrections generally occur on our development server, prior merging these changes on production.
In this particular case, this have been pushed in production ***within the next 1.2.12 release*** following strictly our development process.
On your message of the 3rd march, every players was on the previous 1.2.11 version of the game (and the minion slayer correction awaiting on our development branch for QA testers team being able to test it correctly before it is pushed in production). Means correction of the minion slayers quest was not live at the moment of your message; explaining why it was still not working.
When @Yzia asking you which SOG version you are using, it is the 10th march, and at this time 1.2.12 went out (with the corrections). It explain why you said you were on 1.2.12 version of the game and surely the minion slayer problem was no more present at this time. And I suppose in the meantime minion slayer quest have been achieved as it is no more in your account.
To be sure, I restarted testing the game from the very beginning untill having the two first minion slayer quests, the first with 40 enemies to kill goal and the next one with 100 enemies to kill. I achieved both of them without any calculation errors.
I'm not managing anything about any conpensation about the encountered problems and any loss you faced because of it. But I'm sure @eds_Yzia will manage this fairly.
Be sure we are taking our responsabilities very seriously and are very glad of it as every weeks brings new challenges for the development team that is very dynamic. Now, in every development team, developers produce bugs. I can say there is no bug free in any game or from any developers. If you know some (developers or games) that do not have or produce any bugs, I'll be curious to know them.
Belong this, we try to follow strictly a precise workflow, from having Game Designer throwing ideas and mechanisms for the game, sent to the developers when design is achieved, these developers (including me) completing these tasks following the "Agile" methodology and finally QA testers being able to test every parts of these new features and check if this breaks anything else on the game.
But far as we are taking care of the whole process, remaining bugs could belong here and we try to reduce this amount near zero and listen carrefully the community to correct it as soon as possible in the meantime.
About corrections, It's important to know it's not resolved instantly in the period -> when we receive reports and -> when the correction occuring; because we are maybe involved on another important tasks and we need to prioritize every request we are receiving.
I could add that it have been decided recently to rewrite the whole Quests System to improve it and it is currently on work at the time I'm talking about it.
Be assured we always try to do our best and to be as reactive as possible.
I apologize for the time required for this correction and hope everything will go well in the future on your SOG experience.
