I've been getting a lot of slowdowns for quite some time now, and I can't figure out what could possibly be causing them. It constantly reduces the 5 day increments, going as low as 20 hours occasionally but mostly swinging from 1 day to 3 days. I thought it was caused by a hostile ship sitting in the middle of nowhere that was discovered due to a new deep space tracking station, but these interrupts are still occurring and I have no idea what they'd be caused by.
Should I just build level 10 DSTSs everywhere in an attempt to find these ships? Or could they be caused by some undiscovered alien race that is outpacing another race?
