Request: Make old maps scale to end game level

[Valkyrie_Lenneth]

Is it just me, or do the old maps spawn portals less often?
I wasn't around to do them when they were new, so I'm asking both about if they were nerfed or if the newer ones just spawn portals more.

Its all RNG. I've gone a whole night without seeing one of the new portals, and gotten 5 in a row on the old maps.
