Bug - Normal Some relics are disappearing

[BjDonDoni]

It happened to me the week before last, and it haunts me to this day. Almost every time I receive one relic, it disappears, now I have taken the relic from the placement and it is missing, please fix this error. Some relics are disappearing

Is this issue occurring only with your deployment relics? Or every relic in general.
If you are referring to deployment relics then there is likely some confusion here. They are only awarded based on a percent chance that is determined by the fighters you assign to them. They aren't guaranteed rewards unless you manage to increase this percent chance to 100%. This percent meter is visible while assigning fighters.
