If one uses the Wings of the Sniper mutation and then checks the inventory of the character it shows that this mutation is fully charged. However, this is not the case when checking the recharge on this mutation in combat. This applies to both Dux and Farrow.
I haven’t noticed this issue with any of the other mutations.
PC Platform… But I am unable to determine the version number. I can’t see it on any of the in game screens, nor via viewing version information in Windows File Property. I did just get an update via Steam, but the bug still exists (also applies to non-upgraded Moth Wings).
Closest I can find to version is:
