Ancient Scepter/Spotter: OVERLOAD skill reverting to Spotter: FEEDBACK after activating when used with RealerMysticsItems

[Leafyon-source]

EDIT: The cause of the issue has found to be RealerMysticsItems, when used alongside SniperClassic and AncientScepter, causes weird skill issues with the Spotter special, see video below for details.

When using your Spotter when you have the Ancient Scepter item, the skill icon is replaced with the FEEDBACK base version, and will do FEEDBACK'S 50% dmg to enemies, instead of the OVERLOAD's 100%. You can run your spotter out and back and it will be reverted to the intended OVERLOAD version, although sometimes this ends up not working, until the effect is used again and so on. I thought it was a visual bug at first, but turns out it's a gameplay issue as well.
Here's video for easy understanding, apologies for the game lag, but it demonstrates what I'm saying in terms of the damage numbers fluctuating from 227 to 113 whenever the perk is set to FEEDBACK.
