As the title suggests, I've found that once you've unlocked Nano Recharge you don't need to have it equipped for it to count when you restore to full health after taking damage towards upgrading the module. At first this seemed like it was obviously a bug, but the description for how to upgrade the module only mentions restoring to full health after taking damage with no mention of needing Nano Recharge equipped (while all the other module upgrade requirement descriptions mention having those modules equipped at the time).

Assuming that this isn't only happening to me (that would be terrible), is it a bug or perhaps has a dev realised the requirement was very annoying and sneakily made it easier to get without telling their superiors.

I noticed this as well. IDK if its a bug but ya I'm getting it too. If you had to have that bich equiped man it would take a while to get it up because I'm lvl 50 and it still isn't maxed.

yeah i'm lv40 and its till 700/1500 ...
and i think its not a bug because its not written that is has to be equipped.

And besides it takes quite a while to regenerate that many times...
