I'm not sure how to describe this, but this is what going on.
I left the game with stable "battle power" in 74 - 40-50%ish (I can keep up my position for a whole hour without needing to use skills). I wake up and start the game, but I retreated a few times without touching anything (just looking at the condition of my crews), as if the autocannon hits me harder than before. I checked up if anything happen to my shield modifier (reactor being the usual culprit, v device, and synth mod) but they're online. This happened until 73 70% which is a BIG setback and I'm pretty sure something is wrong.
Initially just wanted to check if Crew XP shard is doing the issue or not (because the level up bar timer went crazy high to 9h), I removed it from Green and put it back up.
Suddenly my "battle power" is back and I keep slicing them until I recovered my position on 74 - 40-50%.
What's going on?
Unfortunately I didn't screenshot numbers, but since this is the 2nd time happening (first one was long time ago when I first arrived at 71 I think), I'll take it next time it's happening.
