... Your suggestion is for the GAME DEVELOPERS to change THEIR game to satisfy your dissatisfaction with a mod you downloaded? How does this make sense at all to you?
Yep, auto attack is the default on mobile, and as Ellajoy said there's no indication a mod was used. How about being decent/nice instead of being toxic for no good reason? Toxicity drives people away, being decent to others helps communities grow. Would be nice if the forum kept growing.
It is a bummer to have the auto-attack default to the scythe. The way around this issue for me is to always have my sword active (I usually play with a controller paired but would work without one paired too) and then I just use touch to tap on the mine rocks I want to break. That way, the game rapidly and automatically switches my current tool (sword) to the pickaxe only for breaking rocks then always auto-switches/defaults back to my sword when bad things attack. The other workaround you can try is to build a
chest in one of the safe areas (that a villager wont walk over) and leave your scythe there when you go in the mine. It is not ideal, I agree that this should be fixed to default to strongest weapon.
I do think this is a mobile bug, it does pick the lame tool automatically otherwise, and in the worst possible places like
skull cavern. I could almost swear the order of my slashing tools affects this too but I'd have to double check that.
