System Information
Operating system: Windows-10-10.0.18362-SP0 64 Bits
Graphics card: GeForce RTX 2070 SUPER/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 442.92

Blender Version
Broken: version: 2.90 (sub 4), branch: master, commit date: 2020-05-27 10:07, hash: efa4ae17f0
Worked: (newest version of Blender that worked as expected)

Short description of error
I have set up a simple scene with mantaflow. There is 1 domain, 1 body of fluid, and one flow source. It was working for a while, but the effector (volcano) stopped effecting the fluid at around frame 100. I added a physics domain to try and address this and tweaked a few settings and now when I try to run the simulation, nothing happens. The first frame shows the particles, but nothing changes after that. I removed the physics domain, still doesn't work.

This is not a well formed bug that I can just reproduce every time, but this sort of things happens A LOT with mantaflow and makes it almost completely unusable. I have wasted more time trying to get my simulations to run than I care to think about. Someone need to look into this or just take mantaflow completely out of the release to save everyone a lot of grief.

Exact steps for others to reproduce the error
Use mantaflow in a production setting for any length of time. Something will go wrong.

[Based on the default startup or an attached .blend file (as simple as possible)]
