Mods or on height level of missions you havent mass limit

you can go into teh server .int file in your game glaxy safe folder and change the mass limit to be much higer if you want! its actly a server.int configrable vaule that you don't need mods for. just change the nubmer mulplayer for max ship mass to be like a few thoduns times higer or somehting like that if you want to.

it might not complty remove the limit but it can make it so you can have huge ships into the rifts and you can change it to be evene higher and tkinker with it a bit for finer adjustments if you want. but becaerfe it will aslo make the lager xendon rift bosses in thsoe rift missions also scale up too however and can get very very very very very very laggy if your not careful by the way.

but bear in mind geting it to dock to teh rift gate might get a bit more akward however so ther that as well.
