Tank Cannon Pivot Problem

I had recently finished setting up my tank, and all looked good except the pivot point for the barrel was in the wrong location. So moved the pivot point to the correct spot in Blender and re-exported into UE4, replacing the old barrel with the new one in the Component section.

Now for some reason, the barrel no longer pitches up down as it did before, instead it just spins in one direction? I’ve triple checked its Event Graph, and nothing has changed, so I dont really know whats going on here.

Followed this tutorial

Looks like the barrels x axis is off by 90deg. can be fixed or compensated for in ue4 but you should go back into blender and export it again with the correct orientation.
