Spartan revive bug

At times, I’m forced to restart to last checkpoint in the campaign due to this bug. If a spartan is downed in the campaign (mainly by brute chieftan or leader powers), he can’t move normally after being revived (this is on xbox, not sure if it’s on pc or not). The only way to move the spartan is to use his slam ability. Which means you either have to wait for a vehicle to get close to hijack or you’re forced to leave them for the mission.
