The encounter rates are indeed low, because they are active from the start of a new game and should be reached over a longer playtime!
since many people play with already maxed saves, this obviously creates an issue
on the other hand getting your game flow broken every few clicks would be another problem!
so a mod boosting the encounter chance to 100% could be considered…
Maybe I will add it to the cheat mode at some point!
Everyone being on a fresh start: would be really curious how many of the encounter you find along the playthrough without fishing for them!
That way I could boost the rates accordingly
