[SPOILER] I killed and butchered the Tarasqe but it dropped it's icor inside a wall

[Seatbelt]

Does the Tarasqe ever respawn or am I going to have to go back to an earlier save?

[MechWarden]

It will respawn.

Also there is a change that after leaving or reloading the game that icor will pop back up from whatever void it fell into.

Lastly, what earlier save? Currently there is no quick saves or backup saves.
