well, in response to the gem/exp quests.... here's what i recorded day 1 of these things:
that's why i said that only dark is in gold ore, only light is in gem, and you get 3 enemies each wave totaling 9 encountered...
i haven't touched gem quest much (i got almost 600k gems after all), but i haven't came across any issues when i tried it. as for exp, been grinding the hell out of that and NEVER saw issues...
but this is going by the "2 times only" quests (and the all day cave of gold ore)
actually, you need to read again cause i said:
new gem quest is only supposed to spawn light mobs
meaning dark mobs should NEVER be factored in... as in, there shouldn't even be holes... just 3 light mobs EVERY SINGLE WAVE FOR ALL 3 WAVES
as in 9 light enemies total, no dark ones at all for gem quests....
the "2 times a day" version should have gotten the same treatment as the one that's open for 30 mins....
