So i recently started playing hentai heroes, and girls would drop fairly often vs bosses. It would usually take me until the end of a world to get all the girls, and if there was an event i could probably get it too. However all of a sudden this stopped about a week ago (a little before the sports event) while going through invaded kingdom i got the housemaid and regine halfway through the world, but then i couldn't get anymore. So now i am half way through juy sea and have none of the girls from edwarda and still havent gotten the last girl from gruntt. Additionally during the sports and epic days event i couldnt get any girls, despite challenging the same boss in each event about 200 times each. Now there is a new event and I still cant get any girls. Is it normal to go through a drought like this? If it is RNG then this theoretically shouldnt happen which confuses me. Can anyone explain to me what is going on?
