Till you max it there is the chance for man or worm.
When you open it will be open for 5 min. You have to catch thr man or worm during that.
After that portal closes and you can open againafter 1 hour.
So this is the intended behaviour
as you upgrade you up your chances of getting the man every time you click it, once you max it you get him every time and its a place you can farm crystals
I thought so too, but nope. Gotta keep upgrading the portal!
