Revert change to reach Monolith: Epsilon (20 Dendroids is too difficult)

Shegolskoe has lots, mostly in the south

Many thanks for this - we came across 9 in Shegolskoe: Overgrowth following a dendroid spawn map made by someone. However, I think it goes to show that many players won't have access to that map, and the overall grind has massively affected the pace of the game up to this point.
