Worked: (newest version of Blender that worked as expected)

Short description of error
Mantaflow ignores obstacles when resuming the bakingprocess

Exact steps for others to reproduce the error
Create a fluidsim with an obstacle. pause the baking and resume ist. Mantaflow ignores the obstacle since the Point of resuming.

#75729.blend

Open blend
hit Bake Data
hit {key Esc} at something like frame 25
hit Resume
let it bake till the end
inspect the bake --> particles start falling through the Collision Effector (Sphere) from the frame where bake was resumed...

See the photos here: Archive.zip
a is the uninterrupted baking, b is interrupted at frame 8. So frame b9 b10 b11 ignore the sphere.
File + two cache folders: https://drive.google.com/file/d/1e_0l3d3H5dn8qt3lQtdn2TOJ8eJPmTQB/view?usp=sharing
both have the same name except that the uninterrupted cache folder has an extra 1 in the end.

This needs a sample file, we need to stop accepting these reports with incomplete information.

@ankitm thanks for helping with triaging, but if you are to do the work from the report, we still need the basic information, a simple .blend file to reproduce the issue, and images attached to this task.
Files hosted externally are not valid.

@lichtwerk if this is confirmed, then again, I would expect the task description to have all the information required to reproduce this (e.g., the .blend)

Confirmed in today's builds (8cb10c124e)

I had in fact created another task (#75851) before realizing it was a duplicate.

Closed that one, I report the reproduction steps here ↓

Exact steps for others to reproduce the error

Note: because of #75850 the order of operation here is fundamental to reproduce

Default file. (Activate X-Ray)
Default cube: Add: Fluid > Effector
Add Plane. Move up Z +2.
Add: Fluid > Flow > Type Liquid; Flow Source > Is Planar
Add new cube at origin. Scale up by 2.5.
Add: Fluid > Domain > Type Liquid
Cache type: Modular. Frame end: 10
Bake Data
- The effector is correclty taken into account
Cache frame end: increase to 20
Resume
- The effector is ignored from frame 11 onwards

@sebbas see also #75758 - shouldn't this have been fixed in 2.83 branch?

Similarly to #75758, this issue should be resolved since cdc399a055. So closing this report, thanks for reporting!
