Some questions:
1) What causes the bags with items in them to drop? It seems sometimes they drop when the current block is mined to 0%.
2) When those items drop, do they stay until collected or do they eventually time out and disappear? (The wording of some researches seem to indicate they time out unless you have researched ways to make they stay longer/infinite time?)
3) Same two questions when ... not certain what to call them, but those "chunks" of "bonus" ore that drop. Those seem to drop at certain "milestone" percentages, but I have not watched close enough to see which percentages.
4) The paper doll for my hero shows multiple equipment, including an additional slot for a second hand weapon. How do I obtain those?
5) I have only "refined" twice, since there is very little in ways of information or guides on how those mechanics work. Could you give some additional information on that?
6) Could you explain what some of the terms, abbreviations, and acronyms mean? Like OpS, OpC, etc? (I can figure out some, but no all.)
Ideally, post these kinds of information in the game description for all new players to see, not just as an answer to my post.
