I'm not sure if this is an issue in not gfb, but I know that calamity is causing the issue because of some testing.
As you see in the picture, the lava does not move for a long time. It then abruptly moves very fast and settles.
#Liquids are extremely slow in singleplayer and multiplayer in gfb

it does the same thing in both singleplayer and multiplayer, and calamity is the only content mod

Seems to be happening to a lot of people
My best guess is that the weird abyss generation is causing some liquid lag
