Hi! Sorry, this error is caused by the Yuri Void Warfare Doctrine hullmod all yuri ships have. I've fixed it on my side, but I can't actually release the fix for you anyway because the mod is already incompatible with older saves even in its WIP state... If you wish to be rid of this problem, I'm afraid you will have to remove all YRXP ships in your fleet. I'm not sure if it also causes a slowdown on the overworld, but if it does, it'll come from YRXP fleets... my apologies for the inconvenience.
Thanks for the quick reply! It does cause overworld slowdown, at least in my case (I checked over a 2-month ingame period, whenever the stutters happen, the log is flooded with those YRXP messages, and when the stutters stop, the most recent messages are just normal (N)exerelin stuff). Oh well, it was a good run.
I had the idea of having caparice and its fleets get into an "accident" (*cough* saturation bomb *cough*) ASAP on my next run (as pirates/legio, so it "fits" lore-wise) to prevent the issue, would that work?
Otherwise it looks like disabling YRXP in my next run is the safest way to prevent this issue from happening again. Bye-bye Adv Ballistics and pretty fireworks
Bug aside, love your mods! Looking forward to the fixed YRXP mod, and will have to try Royal Azalea soon!
