Description:
Reward tokens are set on Yieldoor manually, which means there is a window where rewards may be added in the Gauge, but they weren't yet added on Yieldoor.
Recommended Mitigation:
Rewards are never lost as they can be claimed next week in the following ShadowStrategyGauge::collectGaugeRewards() call, but it can still go a week without claiming them. It may be managed by always verifying the current rewards before calling ShadowStrategyGauge::collectGaugeRewards(), but this is not 100% flawless.
