I was doing the Fake Papers quest (defend the 3 dudes XD ) and my current skills are
4 in Muscle Memory
3 in Arrow Deflection
1 in Precise Blows

I was lucky enough to drop a Nekkar Warrior Red Mutangen from the nearby cave,so my atk power jumped
to 300 (due to the 20% bonus granted by the 3 linked red skills) for Silver Serpentine Sword (Viper set from Orchard).

Here the issue:
I've used a Thunderbolt potion to kill all the incoming Ghouls and complete the quest,so as soon as
I've done it,I made a new savegame,but a portion of the atk power bonus granted from the Thunderbolt potion was still active and retained on my silver sword (ofc the effect wasn't active)
plus if I reload and remove/ put on again my Nekkar Mutagen, my atk power move from 300 to 342... like a perma buff .... but that could lead to an op Geralt due to this glitch/bug.
I've sent my savegames to the support (the clean one and the other with the active bug),and atm I''m not playing at all in order to not screw my 1st run XD.

Anyone got something similar and fixed it ??
