I tried what you suggested Bejaymac but it didn’t change anything

When fired apon the hitbox seems to work fine, each section of the ship registers hits correctly and there are no extra sections that don’t correspond to the CMP. The only two visible issues seem to be the ‘target box’ around the un-selected ships and the ranges that the ships register at so it’s not a critical issue, just a really big pain.
