Excavation mini game difficulty has not decreased with tool

Hi,

I did excavating yesterday and noticed that mini game lvl 3 idfficulty didn’t decrease with my expert tool, it was much easier before the patch.

Thanx in advance!
tool

Unequip it and equip it again to fix this.

It doesn’t fix it, I use 2 tools and equip this one when I do mini game only. Other one is a super armor.
