Lich's keeping Endo caches

[(XBOX)NCC Equinox]

This is a bug I have made a post about previously but basically you find the caches in sabotage style missions or missions that have caches in general and the lich(s) will steal them. Now I get that this is in their behavior to annoy you but it would be nice if they actually returned the caches when you confront and get rid of the lich or lich's in question. I recently lost 1.8k Endo due to a lich stealing the caches and not returning the caches after the final confrontation. These are the only rewards they don't return if they steal credit caches those get returned like intended.
