Artifacts Become Unusable During Stealth Builds

When playing a stealth build, some artifacts can suddenly become unusable. For example, artifacts assigned to slots 1 and 2 may still work, while the artifact assigned to slot 3 cannot be activated. This can be temporarily fixed by unequipping and re-equipping the artifact. However, the issue occurs frequently during combat, making stealth builds extremely difficult to use effectively. Please investigate and fix this issue.
