BEX Slow travel times after 3041

Happens every time I play Career. Does not matter when I start, but after 3040 the travel time between systems is like a slide show. It makes no diff if I use “stopWastingMyTime” mos, or if I manually alter the SimGameConstants myself. So I’m wondering where the culprit could be?

danke

ok new update:
just started a new “career” starting 3047…and everything runs fine. So either the BEX mod or the vanilla game slows down after many years of playing in a career. But what would cause this to happen???
