Max allowable timewarp seems to only be 100000x on a 10.625x GPP save. Going into Kerbal Construction Time's settings and trying to increase max timewarp there doesn't work past 100000x

is this something that works without SD but fails when SD is installed?

I saw you opened and closed a very similar issue on GPP github, did you manage to solve your problem with SD as well? or are you still experiencing this weird bug?

still working on getting that save working well but did fix that particular issue. at first it seemed like it was this mod but now I'm not sure... a clean install from vanilla fixed everything, the timewarp issues and the connection issues i was experiencing. will close this now :)
