Relic rewards vanish after host migration change

[MysticalMoo]

Bit of a tongue twister topic start, Ok was doing a mission on Earth a defense mission which i used a lith relic on, All was going normally until the end of the first set of 5, i chose a blueprint so did the others in the team, host then decided to exit while 3 of us stayed on. Mission then host migrated and on return defaulted to a normal defense mission even though on my HUD i saw Relic amounts still showing as a ticker. Grineer did not drop any more relic energy and upon the next stay / exit screen we saw that the previous blueprint reward had now left our inventory. Item is still not in inventory when returning to lander. Guess this is a new? bug for update 20.2
