Drop limitation of astrolabes and mirage map

Long story short: it seems, that astrolabes can not drop within shaped maps and "full mirage" maps cant drop within such maps.

I do hope, that it is a bug, cause otherwise this continuing thread of "u need to farm T16 to farm T17 cause T17 can not drop T17" is really really disturbing.

Astrolabes and full mirage maps are a very big chunk of overall late game solo profit atm and losing it kinda negates most of the profits from shaped regions and|or full mirage maps farming.
