No Man´s Sky Message Board  

Only problem I've come across so far:

When you use Toxcity Hazard Protection or Life Support, the entire HUD will disappear. Icons will still be on screen, as will the compass. However, the planet name, and all other hud elements disappear.

this is a normal game mechanic by the game. it no longer updates you if nothing is changing and removes these HUD items. The trainer is doing nothing that would affect the display of the HUD

best,
Cal
