@Spess Mahren: Hey, sorry it took me so long to look into this. I couldn't reproduce the issue on my end, but, after looking through the related code, I think this issue might be caused by failure to load the blacklist (which could be caused by any number of things. After loading up your save, can you search the log for an entry that looks like this?
191898 [Thread-4] ERROR ruthless_sector.BattleListener - Error reading data/config/ruthlesssector/faction_rep_change_blacklist.csv
If so, that and the few dozen lines below it should provide us with some insight into what's going wrong.
I just made sure this type of error will be displayed prominently in future versions.
@Arcagnello: Glad you're enjoying yourself!
Yeah, the probe sentries are pitifully weak, which is why this mod gives them the ECM bonus. Making them a bit tankier could help a bit, but I feel like it would just slightly delay the inevitable, and I prefer not to interfere with vanilla more than necessary anyway, so I'd probably just increase their ECM if I wanted to make them more challenging.
