Spawned Lava does not tick

cannot reproduce, provide seed

Here is the seed:
Seed: 3011860941843459521

When I reloaded the world the lava started ticking after about 10 secs.

can you also provide cords?

can confirm with water in that seed, could be the lag when creating the world trough
BTW got a resoursepack on, that's what you see on the left

ok.. i see... i wasn't sure if it was lag or just a glitch...

go 2 in one shot, no lag was there
confirmed

water is ticking like usual... but it took a bit... and lava is still not moving(loaded new world)

Confirmed.
